桩—土—筏共同作用下的沉降特性研究

针对影响建筑沉降和差异沉降的主要因素,以桩筏基础为研究对象,通过土体改良,增加筏板厚度和刚度,改变桩长和桩间距等,采用大型有限元分析软件ANSYS建立模型并计算,与实测数据相对比,得出有益结论。

Study on the settlement characteristics under pile-soil-raft combined action

Aiming at the main factors influencing building settlement and differential settlement,with pile raft foundation as research object,through soil body improvement,increasing raft thick and rigidity,changing pile length and pile interval,the model was built and analyzed with large finite element software ANSYS,compared with measured data,the favorable conclusion was obtained.
