摘要
结合广东省佛山市某基坑工程实例,采用有限元数值模拟的方法对T型地连墙支护体系的变形及受力特性进行研究,并以典型支护剖面模型为基础,分析竖向预应力锚索在控制T型墙变形过程中的作用,同时对比分析在不加竖锚的情况下T型墙与等刚度一字墙的变形特点,提出了一些有益的结论,可为类似工程设计提供参考。
Combining with an instance of a foundation pit engineering in Foshan,Guangdong,to study the deformation and stress characteristics of T-type diaphragm wall supporting system by using the finite element method for the numerical simulation analysis,then based on the typical model supporting profile,analysis the roll of vertical prestressed anchor cable in controlling the deformation of T-type diaphragm wall,and comparative analysis the different deformation characteristics between T-type diaphragm wall and the wall with same stiffness in the case of without vertical prestressed anchor cable,then put forward some useful conclusions to provide a reference for similar engineering design.
