【正文】 natural building materials. Chinese in the eleventh century BC and the early Western Zhou Dynasty to create 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 soil better than mechanical properties, can local materials, and easy to manufacture. The appearance of brick and tile people begin extensive and substantial in construction of housing and urban flood control projects. This civil engineering technology has been rapid development. Up to 18 ~ 19 century, at up to two thousand years, brick and tile has been a civil engineering building materials essential for the human civilization has made a great contribution, and even at present is also widely used. Steel substantial civil engineering applications are the second leap. 70s start the seventeenth century the use of pig iron, the beginning of the nieenth century the use of wrought iron construction of bridges and housing, steel this is a prelude to appear. From the beginning the middle of the nieenth century, metallurgical industry, smelting and rolling out of high tensile and pressive strength, ductility, and the quality of uniform building steel, and then produce highstrength steel wire, steel cable. Therefore necessary to adapt to the development of the steel structure has been booming. In addition to the application of the original beam, arch structures, the new truss, frames, grid structure, gradually extended the suspension structure, a structural form flowers Zhengyan situation. Building longspan structures from brick, stone structure, wood structure a few meters, the development of tens of meters to 100 meters of steel structures, a few hundred meters until 1000 meters above modern. So at Dajiang, both shelves starting Bridge, starting at the ground on the construction of skyscrapers and highrise tower, and even laying on the ground under the railway, to create an unprecedented miracle. 9 In order to meet the needs of the development of steel structure engineering, at the basis of Newton39。 followed by the adoption of the Additional engineering facilities in the local decorative reflected. Engineering facilities and decorative shapes can also show places style, ethnic style and time style? Civil Engineering at the longterm practice, people not only to the building housing the arts to give considerable attention, and achieved outstanding success。 on the other hand, are all areas of society 6 for the advancement of Civil Engineering has created favorable conditions. Such as building materials (steel, cement) implementation of industrial production, machinery and energy technology, and design theory of progress are provided for the Civil Engineering Materials and technical assurance. Thus this period has been rapid development of civil engineering. Emerged around the world at largescale modernization of industrial plants, skyscrapers, nuclear power plants, highways and railways, largespan bridges, largediameter pipelines, long tunnels, the Grand Canal, big dams, big airports, major seaports and marine engineering and so on. Modern civil society continue to create for mankind a new physical environment, human society and modern civilization has bee an important part. Practical Civil Engineering is a highly practical subject. In the early days, through the Engineering Practice of Civil Engineering, sum up successful experiences, especially the lessons learn from the failure of developed. From the beginning the 17th century to Galileo and Newton as the forerunner of modern mechanical and civil engineering practice, and has gradually formed material mechanics, structural mechanics, fluid mechanics, and rock mechanics, as the basic theory of civil engineering disciplines. This Civil Engineering from the experience gradually developed into a science. Civil Engineering at the development process, engineering practice and experience often first in theory, works often show that the accident was unable to foresee that the new factors, triggering a new theory of the research and development. So far, many works deal with the problem, is still very much rely on practical experience. The reason why the development of civil engineering technology major with engineering practice rather than by virtue of scientific
