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。
The structure and supporting principle of the new type of truss retaining wall are introduced. At the same time, the application of large-scale finite element analysis software ANSYS to the truss retaining wall project is analyzed. The results show that the truss-type retaining wall changes the lower pile foundation from the traditional bending-based structural system into tension and compression structure system, which improves the material utilization rate and reduces the construction cost.
