摘　　要：采用Goodman单元模拟桩土界面的相互作用 ,利用有限元分析方法对倾斜荷载下群桩的受力特性进行探讨 ,并开发出适用于各种荷载形式的计算程序。工程实例分析表明 ,该方法能充分反映桩土作有机理及群桩作用效应 ,具有一定的理论意义与工程实用价值。In this study, Goodman Element was used to simulate the interaction between pile and soil; the behavior of pile group under inclined loads was discussed in detail depended on FEM; and a computer program was developed with consideration of various types of load. Applications to engineering practice showed that the method presented in this paper could fully reflect the mechanism of pile soil interaction and the effect of the group of piles, with theoretical significance and engineering values.
