为合理应用决策数据中不同专家的背景知识，找出地铁施工过程中安全测评体系的关注重点，根据地铁施工的特点和SHEL安全模型理论，建立以人-软件（LS）、人-硬件（LH）、人-环境（LE）和人-人（LL）4个环节为基础的钻爆法地铁施工安全指标体系。请专家给出指标语义评价等级和指标权重语义评价等级，并根据其与三角模糊数的对应关系分别得出三角模糊数评价值。针对不同专家的重要性程度差异，提出基于三角模糊数的群一致性评价方法，得出专家综合权重，集结评价数据，最终得到安全评价结果。最后，对青岛地铁1号线过海段进行实例分析。结果表明，该方法可以解决群评价过程中专家个体权威与群体共识难以兼顾的问题，能够充分利用群决策中的原始评价信息，提高地铁施工安全水平评价的准确性。

A safety evaluation system of Metro constructed by drilling and blasting method is established based on livewaresoftware (LS), livewarehardware (LH), livewareenvironment (LE) and livewareliveware (LL). The triangular fuzzy values are obtained according to semantic evaluation grades of index and weights of semantic evaluation grades of index given by experts and their related triangular fuzzy numbers. And then, the safety evaluation results are obtained according to comprehensive weights of expert evaluation results. Finally, a case study is made on seacrossing section on Line No. 1 of Qingdao Metro. The results show that the abovementioned evaluation system is rational and feasible and it can improve the accuracy of safety evaluation of Metro construction.
