| 摘 要： | 总结了基坑事故的引发原因,介绍了一种有效的可靠性分析方法——故障树分析法。应用故障树分析法对基坑排桩支护结构体系和放坡开挖体系进行研究,建立了排桩支护结构体系故障树和放坡开挖体系故障树,并通过定性分析,找出了它们的潜在破坏模式。通过对某放坡开挖工程实例的计算分析,说明了故障树分析法在基坑工程安全评价中应用的可行性。

| Abstract: | Deep excavation accidents occur frequently,which result in rather huge economic losses and bring negative effects to the society.In this paper,the reasons of excavation accidents are summarized firstly.Then an effective reliability analysis method called Fault Tree Analysis(FTA) is introduced and applied to the safety assessment of deep excavation engineering with examples of piles-in-row supporting system and slope supporting system.The fault trees of the piles-in-row supporting system and the slope supporting system are built,and qualitative analyses are done for them.At last,a quantitative analysis is applied to a foundation excavating project using slope supporting system,which illuminates the usage of FTA on the safety assessment of deep excavation engineering. |
