基坑不同支护结构的冗余度研究及分析

文章主要以不同的水平支撑体系为例,利用有限元软件,通过建模分析内支撑构件的作用,以及局部构件破坏时水平支撑体系的破坏情况。建议对重要、复杂的基坑水平支撑体系进行冗余度分析,并在施工过程中对关键构件进行重点监测与保护。

This paper mainly takes different horizontal support system as an example, and adopting finite element software and modeling, analyzes the role of internal support components, as well as the failure of horizontal support system when local components are destroyed. It is suggested that the redundancy analysis of the important and complex foundation pit horizontal support system should be carried out, and the key components should be monitored and protected in the construction process.
