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 。
