【摘要】 本文在扼要地综述基坑工程事故引发原因和工程安全评估的故障树分析法之后,对基坑土钉和水泥土墙支护体系进行研究,建立了土钉和水泥土墙支护体系的故障树模型,并通过定性分析找出了它们的潜在风险模式。文中通过对某土钉支护基坑工程事故实例的计算分析,初步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。更多还原

【Abstract】 The common reasons of accidents in foundation excavation are briefly reviewed and the Fault Tree Analysis (FTA) is then applied to the safety assessment of deep excavation engineering with examples of soil nailing system and cement-soil retaining wall. The fault trees for these two systems are respectively composed and corresponding qualitative analyses are done to them. A quantitative analysis is finally applied to an foundation excavating project using soil nailing system, which illuminates a good usage of FTA on the safety evaluation of foundation excavation engineering.更多还原
