Simulation Of Infinite Saint And Interlayer In Foundation And Its Application In Engineering

The problem of simulation of infinite area is always met in civil engineering. So that simulation of infinite area is very important in civil engineering.This thesis is mainly combined of three parts.Firstly, the method and theory of finite element are dissertated. Secondly, the method and theory of mapping infinite element are dissertated. These elements couple with other kinds finite elements easily while being applied. Thirdly, the plane and spatial mapping infinite element of saint and interlayer is suggested and perfected ,which can couple with all kinds finite and infinite element. These elements can simulate the quite long saint and limp interlayer.The infinite element what suggested in this thesis is proved accurate and reliable and economical by analyzing plane and spatial examples.
