摘要
城市轨道交通取得长足发展的同时,其安全问题变得日益突出,为此有必要对其开展系统的安全评价工作。考虑到城市轨道交通系统的特点,提出一种基于三角模糊数的评价模型,并介绍了该模型的理论依据及具体评价步骤。以郑州市轨道交通M线路为工程背景,基于该模型进行了系统的安全评价,得出M线路安全等级为较大,评价结论与实际情况吻合良好。
To solve the safety issues with the rapid development of urban rail transit, it is imperative to carry on safety evaluation.Considering the characteristics of urban rail transit system, an evaluation model based on triangular fuzzy number is presented, and thetheoretical basis and specific evaluation steps of the model are introduced. Taken Zhengzhou rail transit M line as engineering background,the safety evaluation of the system is made by this model. The result shows that the evaluation score is 6.52, which is in the second degree,and the evaluation conclusion is in good agreement with the actual situation.
