| 中文摘要: |
| 地面沉降是地铁盾构施工过程中常见的事故，运用安全系统工程中的事故树分析法，对引起地面沉降的原因进行分析，以地面沉降为顶事件，通过层层向下分析，找到导致事故发生的基本事件，并构建事故树。通过事故树分析，得到各原因事件之间的逻辑关系，并计算出各基本事件的结构重要度，确定导致地面沉降事故发生的主要原因，找出预防事故的关键途径，并制定出有效的安全管理措施。 |
| 英文摘要: |
| Land subsidence accident is rather common in the subway construction process when applying shield method. By using fault tree analysis, the method in safety system engineering and the causes of land subsidence are analyzed. Taking the land subsidence as the top event, the research is to find the basic faults which caused the accident after the layers of analysis, and then the fault tree is built. Through the fault tree analysis, the logical relationship between various causative events is got，then the structural importance of each basic events is calculated out. The primary causes of land subsidence accident are determined, the critical path of accident prevention is found, and the effective way to prevent the ground settlement accident in the shield construction is proposed. |
