基坑稳定性的可靠度分析

Reliability Analysis of Foundation Pit Stability

基于可靠度理论进行基坑支护结构的抗倾覆稳定和抗坑底隆起稳定分析,采用JC法计算2种稳定模式的可靠度指标,并编制MATLAB程序,计算得到基坑失效概率。研究结果表明,应用可靠度理论进行基坑优化设计是可行的。

In this article,the anti-overturning stability and resistant heave stability of foundation pit support structure are analyzed with the reliability theory.The reliability indicator of two models are calculated with the JC method.The MATLAB program is made to get the failure probability of foundation pit.The research results indicate that it is feasible to apply the reliability theory to the optimization design of the foundation pit.
