基于组合赋权-VIKOR 的地铁站 内涝风险评估

为有效地降低和预防地铁站内涝事故的发生，提出基于组合赋权-VIKOR 的地铁站内涝风险评估。首先，从地铁站降雨情况、挡水能力、排水能力、安全疏散和安全管理 5 个方面，构建风险评价指标体系；然后，用博弈论思想，将层次分析法与 CRITIC 法所求得的权重进行优化重组；最后，应用 VIKOR 方法的利益值，确定地铁站内涝风险评估等级。将所建立的模型应用于广州地铁 13 号线地铁站的内涝风险评价中，得出各地铁站的内涝风险等级，结果表明南岗站处于内涝高风险水平，并通过制定有针对性措施，保障该地铁站汛期的安全运营。该方法的评估结果与实际情况相符，为地铁站内涝风险评估提供一种新的方法。

Risk Evaluation of Waterlogging in Subway StationsBased on Comprehensive Weighting-VIKOR Method

To effectively prevent and reduce the occurrence of waterlogging accidents in subway stations, a risk evaluationmodel for waterlogging in subway stations based on the comprehensive weighting-TOPSIS method is proposed. First, theevaluation index system for waterlogging risk in subway stations was developed and consisted of five aspects: rainfall, waterretention capacity, drain capacity, safe evacuation, and safety management. According to game theory, the weights obtainedby the AHP and CRITIC methods were optimized and recombined to obtain a comprehensive weight. Finally, the benefit valueof the VIKOR method was applied to determine the waterlogging risk level of a subway station. The model was applied to thewaterlogging risk assessment of Guangzhou Metro Line 13, and the waterlogging risk grade and ranking for each subwaystation were obtained. The results show that the waterlogging risk level of Nangang station is high. Targeted measures shouldbe formulated to ensure the safe operation of the subway station during the flood season. The evaluation results of this methodare consistent with the actual situation. Therefore, a new method for waterlogging risk evaluation of subway stations is provided.
