内撑式地下连续墙基坑直角角部效应分析

Study on Corner Effect of Underground Diaphragm Wall with Interior Bracing

内撑式地下连续墙具有明显的角部效应,内支撑布置方式会对围护结构的受力性状产生很大影响。通过有限元方法分析了四种支撑方案下连续墙的位移和受力情况,得出支撑的平面间距不宜过大,为内撑式地下连续墙的设计提供理论支持。

The layout of interior bracing has a great effect on the displacement and force of underground diaphragm wall, and the building envelopes have obvious comer effect. The force and displacement of four design schemes were analyzed by using finite element method, the result shows that the space of bracing should not be too large.
