摘要
结合新沟河江边枢纽工程,对T型地连墙支护结构进行力学特性分析。首先,运用等效刚度原理对T型截面进行简化,再采用传统弹性地基梁法对结构内力进行计算,最后,通过ANSYS有限元软件对结构的应力与形变进行计算。结果表明:T型地连墙对比传统地连墙可以更好的控制墙身位移,无论作为临时支护结构还是永久支护结构都具有更强的适用性。
The mechanical characteristics of T-shaped diaphragm wall retaining structure were analyzed combined with Xingou River Riverside Control Project. Firstly, T-shaped section was simplified by the equivalent stiffness principle, then, the internal force was calculated by the traditional elastic foundation beam method. At last, the stress and deformation of the structure were calculated by the ANSYS finite element software. The results show that： the T-shaped diaphragm wall can better control the displacement of the wall compared to the traditional diaphragm wall, and it is more applicable as a temporary support structure or as a permanent support structure.
