Abstract
In the hope of improving emergency management of underground rail transit in rainstorm waterlogging disasters, this study analysed the influencing factors of underground rail transit vulnerability in rainstorm waterlogging disasters. First, the influencing factors were identified from the three dimensions, namely, exposure, sensitivity and adaptive capacity, and an evaluation index system was established accordingly. The DEMATEL method was used to investigate the importance of each factor. Subsequently, the degree of influence was assessed with the AISM method. Ultimately, a hierarchical structure of the factors influencing the vulnerability of underground rail transit in rainstorm waterlogging disasters was established. The results show that S14 safety investment, S2 surrounding hazards, S3 topography of entrance and exit, S5 height of entrance and exit steps, and S6 weather conditions are the key influencing factors. According to these factors, rainstorm water logging risk can be reduced. The research results can also provide a theoretical basis for disaster prevention and mitigation and risk management in rainstorms and floods.
