| 摘 要： | 针对地铁土压平衡式盾构隧道施工的特点，首先运用系统工程学的思想对盾构隧道施工存在的危险因素进行辨识，对地铁盾构隧道施工进行层次分析，然后构造安全评价指标体系，运用泛函理论确定指标层和准则层的权重，使用安全检查表法和作业条件危险性评价法等不同评价方法对指标层的款项进行评价，得出指标层、准则层的危险等级，最后使用模糊综合评判法对准则层进行评价得出目标层的危险等级，形成安全评价模式，该模式可为类似工程施工的安全评价提供参考。

| Abstract: | For the characteristics of metro earch pressure balance(EPB) shield tunnel construction，first of all，the risk factors of shield tunnel construction by using the idea of system engineering are identified，and its levels are analyzed，and safety assessment index system is structured. Then the weights of indicators and criteria layer are determined by functional theory. Using SCL and LEC to assess items of guide line layer，carrying out risk levels of the target and guide line layer，using fuzzy comprehensive assessment theory to assess risk level of guide line layer to reach the risk level of the target，these are used to form a safety assessment model，which can provide reference for similar projects construction. |
