摘要: 本文以有限层法和有限元法为基础，结合荷载传递函数，建立群桩－土－承台结构共同作用的线性和非线性数值分析方法。该分析方法考虑了地基土的成层非均质性和群桩中每一单桩的非线性工作性状等因素。算例和实例表明，在线性情况时，本文方法与建立在Ｍｉｎｄｌｉｎ解基础上的分析方法之间有较好的一致性；当计及非线性时按本方法计算所得结果与实测数据吻合

Abstract: Based on the finite layer method and finite element method, an approach is presented for linear and non linear numerical analysis of pile groups-soil-pile cap interaction This approach can consider the effect of layered non homogeneous soils and non linear responses of individual piles in pile groups For linear analysis, the results obtained by proposed method agree with those based on Mindlin′s solution The computed non linear response of interaction compares favourably with measured results from field tests
