Introduction to Civil Engineering Papers
Civil Engineering for the development of a key role, first as a material foundation for the civil engineering construction materials, followed by the subsequent development of the design theory and construction technology. Every time a new quality of building materials, civil engineering will be a leap-style development. People can only rely on the early earth, wood and other natural materials in the construction activities, and later appeared in brick and tile that artificial materials, so that the first human to break the shackles of natural building materials. China in the eleventh century BC in the early Western Zhou Dynasty created the tile. The first brick in the fifth century BC to the third century BC, when the tomb of the Warring States Period. Brick and tile better than the mechanical properties of soil, materials, and easy to manufacture. The brick and tile so that people began to appear widely, to a large number of housing construction and urban flood control project, and so on. This civil engineering technology has been rapid development. Up to 18 to the 19th century, as long as two thousand years, brick and tile has been a major civil engineering construction materials, human civilization has made a great contribution to the even was also widely used in the present. The application of a large number of steel products is the second leap in civil engineering. Seventeen 1970s the use of pig iron, the early nineteenth century, the use of wrought iron bridges and the construction of housing, which is a prelude to the emergence of steel. From the beginning of the mid-nineteenth century, metallurgical industry, smelting and rolling out high tensile and compressive strength, ductility, uniformity of the quality of construction steel and then produce high-strength steel wire, steel cables. As a result of the need to adapt to the development of the steel structure have been flourishing. In addition to the application of the original beam, arch structure, the new truss, a framework, the structure of network, cable structures to promote the gradual emergence of the structure of Yan in the form of flowers. From the brick building long-span structures, stone structures, a few meters of wood, steel structure to the development of tens of meters, a few hundred meters, until modern km above. So in the river, cross the bridge from shelves, on the ground since the construction of skyscrapers and high-rise tower, even in the laying of underground railway, to create an unprecedented miracle. In order to meet the needs of the development of steel works, on the basis of Newton's mechanics, material mechanics, structural mechanics, structural engineering design theory came into being, and so on. Construction machinery, construction technology and construction organization design theory also development, civil engineering from the experience of rising to become science, engineering practice and theoretical basis for both is a different place, which led to more rapid development of civil engineering. During the nineteenth century, 20, made of Portland cement, concrete has come out. Concrete can aggregate materials, easy-to-concrete structures forming, but the tensile strength of concrete is very small, limited use. By the middle of the nineteenth century, the surge in steel production, with the emergence of this new type of reinforced concrete composite construction materials, which bear the tension steel, concrete bear the pressure and play their own advantages. Since the beginning of the 20th century, reinforced concrete is widely used in various fields of civil engineering. From the beginning of the 1930s, there have been pre-stressed concrete. Pre-stressed concrete structure of the crack resistance, rigidity and carrying capacity, much higher than the reinforced concrete structure, which uses an even wider area. Civil Engineering into the reinforced concrete and prestressed concrete dominant historical period. Concrete buildings to bring about the emergence of new economic, aesthetic structure in the form of engineering, civil engineering so that a new construction technology and engineering design of the structure of the theory. This is another leap in the development of civil engineering. A project to build the facilities in general to go through the investigation, design and construction in three stages, require the use of geological prospecting projects, hydro-geological survey, engineering survey, soil mechanics, mechanical engineering, engineering design, building materials, construction equipment, engineering machinery, building the economy , And other disciplines and construction technology, construction and other fields of knowledge, as well as computer and mechanical testing techniques. Civil engineering is therefore a broad range of integrated disciplines. With the progress in science and technology development and engineering practice, the civil engineering disciplines have also been developed into a broad connotation, the number of categories, the structure of complex integrated system. Civil Engineering is accompanied by the development of human society developed. It works in the construction of facilities reflect the various historical periods of socio-economic, cultural, scientific, technological development outlook, which civil society has become one of the historical development of the witness. In ancient times, people began to build simple houses, roads, bridges and still water channel to meet the simple life and production. Later, in order to adapt to the war, production and dissemination of religious life, as well as the needs of the construction of the city, canals, palaces, temples and other buildings. Many well-known works shown in this historical period of human creativity. For example, the Great Wall of China, Dujiangyan, the Grand Canal, Zhaozhou Bridge, Yingxian Wooden Tower, the pyramids of Egypt, Greece's Parthenon, Rome's water supply project, colosseum amphitheater (Rome large animal fighting Field), as well as many other well-known churches, palaces and so on. After the industrial revolution, especially in the 20th century, on the one hand, civil society to put forward a new demand; On the other hand, all areas of society for the advancement of civil engineering to create good conditions. Thus this period of civil engineering has been advanced by leaps and bounds. All over the world there have been large-scale modernization of industrial plants, skyscrapers, nuclear power plants, highways and railways, long-span bridges, and large-diameter pipelines long tunnel, the Grand Canal, the big dams, airports, port and marine engineering, etc. . For civil engineering continually modern human society to create a new physical environment, human society, modern civilization has become an important part. Civil Engineering is a very practical subjects. In the early days, through the civil engineering practice, summing up successful experience, in particular, to draw lessons from the failure of developed. From the beginning of the 17th century, with Galileo and Newton as a pilot with the mechanics of the modern civil engineering practice, gradually formed the mechanical, structural mechanics, fluid mechanics, rock mechanics, civil engineering as the basis of theoretical subjects. This experience in civil engineering from the gradually developed into a science. In the course of the development of civil engineering, engineering practice often first experience in theory, engineering accidents often show a new unforeseen factors, triggering a new theory of the research and development. So far a number of projects dealing with the problem, is still very much rely on practical experience. Civil Engineering Technology with the main reason for the development of engineering practice and not by virtue of scientific experiments and theoretical studies, for two reasons: First, some of the objective situation is too complicated and difficult to faithfully carry out laboratory or field testing and analysis. For example, the foundation, tunnel and underground engineering and deformation of the state and its changes over time, still need to refer to an analysis of engineering experience to judge. Second, only a new engineering practice in order to reveal new problems. For example, the construction of a high-rise buildings, high-rise tower and mast-span bridges, wind and earthquake engineering problems highlighted in order to develop this new theory and technology. In the long-term civil engineering practice, it is not only building great attention to the arts, has made outstanding achievements; and other works, but also through the choice of different materials, such as the use of stone, steel and reinforced concrete, with natural Environmental art in the construction of a number of very beautiful, very functional and good works. Ancient Great Wall of China, the modern world, many of the television tower and the bridge ramp Zhang, are cases in point.A building is closely bound up with people，for it provides with the necessary space to work and live in .As classified by their use ,buildings are mainly of two types :industrial buildings and civil buildings .industrial buildings are used by various factories or industrial production while civil buildings are those that are used by people for dwelling ,employment ,education and other social activities .Industrial buildings are factory buildings that are available for processing and manufacturing of various kinds ,in such fields as the mining industry ,the metallurgical industry ,machine building ,the chemical industry and the textile industry . factory buildings can be classified into two types single-story ones and multi-story ones .the construction of industrial buildings is the same as that of civil buildings .however ,industrial and civil buildings differ in the materials used and in the way they are used .Civil buildings are divided into two broad categories: residential buildings and public buildings .residential buildings should suit family life .each flat should consist of at least three necessary rooms : a living room ,a kitchen and a toilet .public buildings can be used in politics ,cultural activities ,administration work and other services ,such as schools, office buildings, parks ,hospitals ,shops ,stations ,theatres ,gymnasiums ,hotels ,exhibition halls ,bath pools ,and so on .all of them have different functions ,which in turn require different design types as well. Housing is the living quarters for human beings .the basic function of housing is to provide shelter from the elements ,but people today require much more that of their housing .a family moving into a new neighborhood will to know if the available housing meets its standards of safety ,health ,and comfort .a family will also ask how near the housing is to grain shops ,food markets ,schools ,stores ,the library ,a movie theater ,and the community center .In the mid-1960’s a most important value in housing was sufficient space both inside and out .a majority of families preferred single-family homes on about half an acre of land ,which would provide space for spare-time activities .in highly industrialized countries ,many families preferred to live as far out as possible from the center of a metropolitan area ,even if the wage earners had to travel some distance to their work .quite a large number of families preferred country housing to suburban housing because their chief aim was to get far away from noise ,crowding ,and confusion .the accessibility of public transportation had ceased to be a decisive factor in housing because most workers drove their cars to work .people we’re chiefly interested in the arrangement and size of rooms and the number of bedrooms .Before any of the building can begin ,plans have to be drawn to show what the building will be like ,the exact place in which it is to go and how everything is to be done.An important point in building design is the layout of rooms ,which should provide the greatest possible convenience in relation to the purposes for which they are intended .in a dwelling house ,the layout may be considered under three categories : “day”, “night” ,and “services” .attention must be paid to the provision of easy communication between these areas .the “day “rooms generally include a dining-room ,sitting-room and kitchen ,but other rooms ,such as a study ,may be added ,and there may be a hall .the living-room ,which is generally the largest ,often serves as a dining-room ,too ,or the kitchen may have a dining alcove .the “night “rooms consist of the bedrooms .the “services “comprise the kitchen ,bathrooms ,larder ,and water-closets .the kitchen and larder connect the services with the day rooms .It is also essential to consider the question of outlook from the various rooms ,and those most in use should preferably face south as possible .it is ,however ,often very difficult to meet the optimum requirements ,both on account of the surroundings and the location of the roads .in resolving these complex problems ,it is also necessary to follow the local town-planning regulations which are concerned with public amenities ,density of population ,height of buildings ,proportion of green space to dwellings ,building lines ,the general appearance of new properties in relation to the neighbourhood ,and so on .There is little standardization in industrial buildings although such buildings still need to comply with local town-planning regulations .the modern trend is towards light ,airy factory buildings .generally of reinforced concrete or metal construction ,a factory can be given a “shed ”type ridge roof ,incorporating windows facing north so as to give evenly distributed natural lighting without sun-glare .土木工程专业英语翻译

现代化高层建筑的玻璃幕墙采用了由镜面玻璃与普通玻璃组合，隔层充入干燥空气或惰性气体的中空玻璃。中空玻璃有两层和三层之分，两层中空玻璃由两层玻璃加密封框架，形成一个夹层空间；三层玻璃则是由三层玻璃构成两个夹层空间。中空玻璃具有隔音、隔热、防结霜、防潮、抗风压强度大等优点。据测量，当室外温度为－10℃时，单层玻璃窗前的温度为－2℃，而使用三层中空玻璃的室内温度为13℃。而在炎热夏天，双层中空玻璃可以挡住90%的太阳辐射热。阳光依然可以透过玻璃幕墙，但晒在身上大多不会感到炎热。使用中空玻璃幕墙的房间可以做到冬暖夏凉，极大地改善了生活环境。
Glass curtain walls in modern high-rise buildings use a combination of mirrored glass and regular glass, filled with dry air or inert gas in the insulating glass. Insulating glass is divided into two layers and three layers. The two layers of insulating glass are sealed by two layers of glass to form a sandwich space. The three-layer glass is composed of three layers of glass to form two sandwich spaces. Insulating glass with noise, heat insulation, anti-frost, moisture, wind pressure and other advantages. It is measured that when the outdoor temperature is -10 ° C, the temperature in front of the single-glazed window is -2 ° C, whereas the indoor temperature using the three-layer insulating glass is 13 ° C. In the hot summer, double glazing blocks 90% of the sun's radiant heat. The sun can still pass through the glass curtain wall, but most of the body will not feel hot. The use of hollow glass curtain wall of the room can be cool in winter and warm in summer, greatly improving the living environment.
