摘　　要：通过ANSYS三维弹性有限元的数值分析 ,以CFG九桩复合地基为例 ,研究了在竖向荷载作用下群桩复合地基中承台 -垫层 -桩 -土的共同作用特性 ,对群桩复合地基的桩体荷载传递规律、桩土应力比、沉降及其影响因素进行了系统的分析。Taking nine CFG piles composite foundation as an example and using ANSYS numerical analysis, the characteristics of co-action among pile cap-padding layer-pile-soil in a composite foundation of pile cluster under vertical loading are studied, and load transmission law, pile-soil stress ratio, settlement and their influence factors of the composite foundation are systematically analysed.
