振冲碎石桩复合地基承载力数值仿真与试验分析

On numeric simulation of composite foundation loading capacity of vibro replacement stone column and its experimental analysis

针对新疆某电厂上部结构地基承载力要求,提出碎石桩复合地基加固方案,提出基于数值仿真和现场荷载试验综合确定复合地基承载力特征值的综合方案,解决了确定碎石桩复合地基承载力特征值常用方法的弊端,为类似的工程提供依据。

According to the loading capacity requirements of the upper structure of some power plant in Xinjiang, the study points out the stone column composite foundation consolidation scheme, points out the comprehensive scheme of the composite foundation loading capacity feature value based on the numeric simulation and field loading experiments, and solves the defects of the common methods for identifying the feature value of the stone column composite foundation loading capacity, so as to provide the reference for similar projects.
