中文摘要:
      地铁防涝是城市防洪的重要组成部分,明确暴雨期间地铁站点的防涝情况至关重要。针对地铁防涝风险评价存在的复杂性及不确定性,充分考虑地铁防涝各影响因素,建立对应的防涝评价指标体系,同时运用集对分析理论,引入熵权法和序关系法确定评价指标复合权重,建立了复合权重集对分析模型,并以成都地铁2号线西延线6个站点为例运用该模型进行防涝风险评价。结果表明,各站点运行期间的防涝风险评价等级为Ⅲ或Ⅳ级,防涝情况较良,形势比较乐观。研究结果为地铁运行期间的防涝工作提供一定的参考依据。
英文摘要:
      Subway flood prevention is an important part of urban flood control. It is important to clarify flood prevention at subway stations during heavy rain. Aiming at the complexity and uncertainty of subway flood risk assessment and fully considering influencing factors of subway flood prevention, the corresponding flood prevention evaluation index system was established. Based on the theory of set pair analysis, the methods of entropy weight and order relation were introduced to determine the composite weight of evaluation index and establish compound weight set analysis model. Taking the 6 stations of the West Extension Line of Chengdu Metro Line 2 as an example, the results show that the flood risk assessment level of each site belongs to grade Ⅲ or Ⅳduring operation period, the flood prevention is better and the situation is more optimistic. 〖JP3〗The research results can provide a certain reference for flood prevention work during subway operation.
