通过有限元分析软件ANSYS11．0，对邻近地面堆载作用下已承载CFG桩复合地基的力学性状进行了分析，对已承载CFG桩复合地基中桩体在不同的地面堆载荷载、堆载作用位置、承台受荷状态以及土体压缩模量等工况中的性状进行了研究，进而分析得出堆载的作用位置、大小以及复合地基所在场地范围内土体压缩模量是几个比较重要的影响因素，对临近堆载的CFG桩复合地基的力学性状影响较大。

The finite numerical analysis software ANASYS 11.0 is used to simulate the behavior of the CFG piles which are the parts of the CFG Piles Composite Foundation that influenced by the soil movements from heap loads. The properties of the CFG piles are studied, which is in dif- ferent heap loads conditions, different pile cap conditions and the different modulus of compressi- bility of soil. The results show that the acting position of the heap loads, the size of the heap loads and the modulus＇of compressibility of soil are the main factors that affect the mechanical proper- ties of the composite foundation which is under lateral soil movement due to heaped loads.
