Abstract:

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.
