| 摘 要： | 针对地铁基坑工程环境复杂、影响因素多的特点，提出以故障树分析为基础结合工作分解结构（WBS）-风险分解结构（WBS）进行风险识别的方法。此方法引入WBS-RBS将地铁基坑工程工作分解结构和风险源分解结构耦合判断并说明相应风险因素或风险事件，并按照故障树建树原则根据彼此间的逻辑关系，用逻辑门连接上下层事件，形成地铁基坑工程主要故障树。在此基础上，对风险因素进行敏感性分析并提出相应的预防措施。

| Abstract: | The engineering environment of subway foundation pit is complex with too many influencing factors; and the analysis of risk factors is incomprehensive due to the uncertainty of risk events in the construction of foundation pit. However, up to now, the conventional risk identification method can’t consider all the risk factors. A risk identification method based on the fault tree analysis (FTA) method is proposed to identify the risk factors with the combination of the work breakdown structure (WBS) and risk break- down structure (RBS). The risk factors or risk events are judged and explained by the coupled analysis of WBS and RBS; and then the fault tree of subway foundation pit risk is established. Furthermore, sensitivity analysis is carried out based on FTA; and then precaution measures of risk events in subway foundation pit are proposed. |
