有限元模拟分析承台形式对疏桩基础沉降的影响

摘要

疏桩基础采用井格式承台和筏板承台两种不同形式的承台，应用有限元软件模拟分析了不同形式的承台中心的沉降量，并对等效荷载情况下，二者承台中心沉降量进行了比较，对承台形式的选取提出建议。%The thinned pile foundation adopts two different bearing platforms such as raft and two-way grillage.This paper studied and compared the different settlements of the platform center with different forms on the equivalent load using the finite element software.And some suggestions on the selection of platform were put forward.
