摘　　要：文章采用SWMM建立道路雨水管汇水范围的降雨~产汇流模型,对新建道路方案进行洪水影响分析,找出道路潜在积水点,适时调整管网及道路设计方案确保方案经济合理,并具可实施性,消除项目区受外水影响。同时,在分析结果的基础上,要求设计方案综合考虑采用透水铺装、绿化隔离带、雨水调蓄水池、初雨设施等措施,使降雨尽可能就地消纳或蓄存起来加以利用,减小项目区外排水量,减轻项目建设对周边环境的影响,避免实施后存在路面积水隐患。In this paper,SWMM is used to establish the rainfall-runoff model of rainwater pipe catchment range,analyze the flood impact of the new road scheme,find out the potential pondings of the road,timely adjust the pipe network and road design scheme so as to ensure that the scheme is economic and reasonable,feasible,and eliminate the impact of external water on the project area.At the same time,on the basis of the analysis results,the design scheme is required to comprehensively consider the adoption of measures such as permeable pavement,green isolation belt,rainwater regulation and storage pool,primary rain facilities,etc.,so that the rainfall can be absorbed or stored locally as much as possible to reduce the water discharge outside the project area,reduce the impact of the project construction on the surrounding environment,and avoid the potential water accumulation on the road after implementation.
