摘　　要：车辆基地是城市轨道交通的重要组成部分,且多位于市郊,具有占地面积大、自来水使用成本较高和用水量大等特点。以国内轨道交通车辆基地雨水系统为研究对象,从水源选择、水量平衡和蓄水池容积计算等方面分析了雨水利用的可行性,提出了车辆基地大库屋面雨水经过“初期弃流+模块蓄水池+过滤”处理后回用于道路冲洗和绿化浇洒符合国家低影响开发的建设理念,为轨道交通车辆基地雨水综合利用提供参考。Depots as an important component of urban rail transit systems are often located in suburban areas,and have characteristics such as large land coverage,high costs for tap water usage,and significant water consumption.Focusing on rainwater systems in domestic rail transit depot,the feasibility of rainwater utilization are analyzed from aspects including water source selection,water balance,and storage tank capacity calculation.It proposes that after "Initial Disposal + Modular Reservoir + Filtration" treatment,the collected rainwater from the large roof areas of depot buildings can be reused for road washing and landscaping irrigation.This approach aligns with the national concept of low-impact development and provides a reference for the comprehensive utilization of rainwater in rail transit depots.
