Application of CFG pile composite foundation in window of Chinese characteristic economy

In this paper,combining with the practice of window of Beijing characteristic economy,the construction techniques and precautions of CFG pile composite foundation are introduced in detail.There are many factors affecting settlement and deformation of CFG pile composite foundation,with the use of the finite difference analysis package ABAQUS,these factors are analyzed systematically,including load,thickness and modulus of cushioning layer,length of pile,modulus of pile and the soil around the pile.The relationship between settlement and those factors are discussed,and the methods or measurements of reducing settlement are suggested.
