为了实现城市轨道交通车辆基地选址时资源的高效共享，提升资源利用效率并降低成本，在满足线网检修需求及应急救援需求的基础上，综合考虑了架大修基地和应急救援基地的综合建设成本。首先，利用综合成本计算函数，以最小化建设总成本和待修列车转运里程、最大化应急救援服务水平为目标，构建了“成本-效率-安全”多维度优化模型。然后，以武汉市城市轨道交通线网为例进行算例分析，利用Lingo进行求解。最后，通过灵敏度分析探讨了子目标函数权重和基地数量对选址方案的影响。结果显示，在考虑架大修基地和应急救援基地的综合建设成本后，总建设成本降低1.49%的同时，应急救援服务水平上升了2.98%。研究发现，综合考虑检修资源和应急救援的车辆基地选址问题可以在一定程度上降低建设成本，提升经济效益，促进城市资源的集约化利用。

The purpose of this article was to better achieve resource sharing, improve resource utilization efficiency, and reduce costs when selecting the location of urban rail transit depots. Considering the maintenance and emergency rescue needs, the study took into account the construction costs of the maintenance resources and the emergency rescue. Firstly, utilizing the comprehensive cost calculation function, a multidimensional optimization model of "cost-efficiency-safety" was constructed with the goal of minimizing the total construction cost and the distance of trains to be repaired, and maximizing the level of emergency rescue services. Secondly, taking Wuhan's urban rail transit network as an example, a case study was conducted and solved using Lingo. Finally, the impact of sub-objective function weights and the depot number on the depot location scheme was explored through sensitivity analysis. It proved that after considering the comprehensive construction costs of the maintenance depot and emergency rescue base, the total construction cost has reduced by 1.49% and the level of emergency rescue services has increased by 2.98%. The result showed that considering both maintenance resources and emergency rescue in depot location can reduce construction costs,improve economic benefits, and promote the intensive utilization of urban resources.
