Abstract

The invention provides a subway safety risk and emergency capability assessment method and device based on scene construction, and relates to the technical field of subway risk assessment. The method comprises the steps: performing clustering analysis on historical data of subway accident cases, and dividing subway accidents according to different places in combination with a scene construction theory to obtain a plurality of risk areas and risk scenes; scoring each risk scene through an improved LEC risk evaluation method, and determining a risk level of each risk scene; acquiring an emergency capability evaluation index of each risk scene, and acquiring a score corresponding to each index; based on a fuzzy comprehensive evaluation method, determining an emergency capability evaluation score of the risk scene according to the score corresponding to each index; and according to the emergency capability assessment score of each risk scene, determining the emergency capability level of each risk scene so as to complete subway risk emergency capability assessment. According to the method, the overall emergency capability of the urban subway system can be improved.

Description

technical field [0001] The invention relates to the technical field of subway risk assessment, in particular to a scenario-based method and device for evaluating subway safety risks and emergency response capabilities. Background technique [0002] Recently, due to the frequent occurrence of extreme weather, many subway stations in Zhengzhou City have been flooded by rainwater due to heavy rain, causing serious waterlogging of subway lines. This not only brings great impact and economic loss to the operation of the subway, but also seriously threatens the lives of passengers and related practitioners. According to incomplete statistics, the Zhengzhou subway flood disaster has caused 12 deaths and many injuries. In the face of the rapid development of urban subways and the reality of the surge in passenger traffic brought about by them, how to deal with increasingly frequent meteorological disasters and maximize the protection of the people and the safety of national propert...
