摘要
以"5.12"汶川地震影响严重的地区内CFG桩复合地基加固工程为研究对象,选取典型地基剖面运用FLAC3D模拟历经"5.12"汶川地震的地基的变形、应力及破坏特征,对CFG桩复合地基中CFG桩特性进行分析,并与震后现场建筑物震损特征相比较,评价CFG桩复合地基加固效果,为地震区采用此方式处理地基提供经验。
By researching typical profile of the project of composite foundation with CFG pile in the seriously affected areas of "5.12"Wenchuan Earthquake with FLAC3D,deformation,stress and failure of foundation and characteristics of cushion and CFG pile could be got during the earthquake.Meanwhile,according the situation of building site after earthquake,it could evaluate the effect of composite foundation with CFG pile in order to provide experiences of foundation treatment for the engineerings in the earthquake zone.
