摘　　要：为解决城市轨道交通防汛站选址问题,文章在既有研究的基础上,对防汛站节点脆弱度指标进行针对性分析,并采用熵权法计算节点脆弱度。然后基于节点脆弱度,以线网总覆盖度最大、防汛站建设成本最小以及应急响应时间最小为目标,考虑有关约束,建立基于节点脆弱度的城市轨道交通防汛站选址模型,模型通过赋权将多目标转换为单目标,最终得到一个基于集合覆盖模型的单目标线性0-1整数规划模型,并以武汉地铁为对象进行分析,研究成果能够为轨道交通防汛站选址提供借鉴。To address the issue of site selection for flood prevention stations in urban rail transit,this article conducts a focused analysis on the vulnerability index of flood control station nodes based on existing research,and employs the entropy weight method to calculate node vulnerability.Then,considering node vulnerability and aiming to maximize total network coverage while minimizing construction costs of flood prevention stations and emergency response times,this article incorporates relevant constraints to establish a site selection model of urban rail transit flood prevention stations based on node vulnerability.The model transforms multiple objectives into a single objective through weighting,ultimately generating a single objective linear 0-1 integer programming model based on the set coverage model.Using the Wuhan metro as a case study,the research results offer valuable insights for the site selection of flood prevention stations in rail transit systems.
