Numerical Analysis Of Settlement Of DJM Pile Composite Foundation

With the constant enlargement of the basic civil engineering in our country, and more highways, bridges, houses, and so on, need to be built on the soft ground.There are various methods for managing soft ground,and many economical and effective methods have been widely used in engineering, DIM composite foundation is one of these methods. But the theory of the DIM composite foundation is trailed behind by the practice of the DJM composite foundation. This leads to the limitation of the development of DJM composite foundation,so it is important to investigate composite foundation theoretically.lt has become a hard-of-hearing problem in geotechnical engineering .This paper has analyzed the mechanical properties of reinforced ground by means of model test and the application of finite element analysis software ANSYS. Some basic regularities of the load distribution, deformation characters, and so on, has been gained. The relation between the length of pile and settlement and the relation between the distance of pile and settlement are worked out, which provide thereunder for optimization,then the optimization of DJM pile composite foundation is done by means of ANSYS, the optimum length of pile and the optimum distance of pile are educed.
