地铁站支护结构失效分析与抗干扰极限理论

Failure analysis of support structure in subway station andlimit theory of anti\|interference

鉴于发生多起地铁车站支护结构失效的重大事故,分析其支护结构失效机理与控制方法,采用空间建模研讨地铁车站深基坑开挖过程中支护结构对外界干扰的承受极限。

In view of many accidents of support structure failure in subway station, the paper is to analyze the principle and control method of support structure failure and make a research on the bearing limit of support structure against outer interference during excavation of deep foundation pit in subway station by using spatial modeling.
