摘　　要：以水泥土桩复合地基静载荷试验为原型,采用典型黏土层的非线性本构模型,以ADINA三维有限元对水泥土桩复合地基中的桩身应力、桩间土应力、位移特性等进行计算分析,取得了一些用实测手段难以得到的结果,并将部分结果与实测资料进行了对比分析,可较好地揭示搅拌桩复合地基的荷载传递规律和沉降变形特性。With static load test of composite foundation of mixed-in-place cement-soil piles using nonlinear constitute model of typical clay layer,it was analyzed the shaft stress and interpile stress as well as displacement features of the said foundation by 3-D finte element method,whose results were compared with the measured ones,which can indicate load transfer law and sttlement characteristics of the foundation.
