Abstract

In order to effectively prevent major risks caused by extreme stormy weather to metro system operation, based on literature research and expert interviews, a metro system vulnerability index system under storm disturbance was established from five aspects: people, equipment, environment, safety management and emergency response, and 20 influencing factors were obtained. Then, a formation mechanism model of metro system vulnerability was established by using ISM-MICMAC, and driving force and dependency of each factor were demonstrated. Finally, with Zhengzhou subway as an example, the model was verified and countermeasures were proposed. The results show that the vulnerability of metro system can be divided into 5 layers. Educational training and regulations are the deepest influencing factors, and controlling and scheduling these two factors can alleviate and adjust adverse effects of the others. Staff's operational level and safety management awareness are middle layer ones, while the rest are in uppermost layer of ISM and direct influencing factors. © 2022 China Safety Science Journal.
