浙江某实验大楼基坑坍滑事故的整体稳定性分析

Integrity Stability Analysis on Slip Accident of Pit of a Test Building in Zhejiang

对浙江某实验大楼基坑坍滑进行反分析研究 ,结果表明土钉墙支挡结构不仅存在内部整体滑移问题 ,而且还存在边坡外部深层整体滑移问题。分析表明 ,土钉墙支挡结构边坡外部深层整体滑移破坏特别易发生于软弱地层中 ,设计时应引起足够重视。

According to the anti-analysis research on the slip of the pit of a test building,it is shown that the stability of soil nail wall has not only the inner integrity slip problem,but also the outer deep integrity slip problem.The results show the outer deep integrity slip destroy of soil nail wall is easy to happen in soft soil area.It must be paid attention to in design.
