新型桁架式挡土墙地基承载力计算及工程应用

Calculation on Ground Bearing Capacity of New Truss Retaining Wall and the Engineering Application

对新型桁架式挡土墙的结构组成、支护原理作了介绍,同时,运用大型通用有限元分析软件ANSYS对桁架挡墙工程实例进行了相关受力分析。结果表明:桁架式挡墙将下部桩基础由传统的受弯为主的结构体系改变为受拉、压结构体系,提高了材料利用率,降低了工程造价。

For the new truss retaining wall developed, the structural composition and support principle thereof were introduced herein. The mechanical analysis related to the actual example where the truss retaining wall was applied, was carried out with the large-scale general finite element analysis software ANSYS. The result shows that, truss retaining wall, which changes its lower pile foundation from traditional bending structural unit to tensile and compressed one, may improve the ratio of material utilization and reduce the project cost.
