【正文】 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 highrise 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 Newton39。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 bee science, engineering practice and theoretical basis for both is a different place, which led to more rapid development of civil engineering. During the nieenth century, 20, made of Portland cement, concrete has e out. Concrete can aggregate materials, easytoconcrete structures forming, but the tensile strength of concrete is very small, limited use. By the middle of the nieenth century, the surge in steel production, with the emergence of this new type of reinforced concrete posite 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 prestressed concrete. Prestressed 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, hydrogeological survey, engineering survey, soil mechanics, mechanical engineering, engineering design, building materials, construction equipment, engineering machinery, build
