摘　　要：为解决天津市老旧城区强降雨时带来的积水问题,需对低标排水系统提标改造,提升城市的防汛防涝能力。文章以天津市河北区王串场地区积水片改造工程为例,详细介绍了工程设计方案,并通过InfoWorks ICM水力模型对排水系统的管网水力条件和区域积水风险进行评估,结果表明:雨水设计重现期3年时,提标改造后的雨水系统区域内基本无积水产生,部分管道虽然处于超负荷状态,但是水位线都处于地面高程以下,基本满足雨水排放要求;雨水设计重现期100年时,区域内涝积水范围、积水深度和退水时间都有明显降低。针对设计中遇到的问题提出合理的解决方案,可为类似的中心城区内涝积水片排水系统提标改造设计工作提供借鉴和参考。To solve the waterlogging problem caused by torrential rains in the old urban area of Tianjin,the low-standard drainage system needs to be upgraded and reconstructed to improve the urban drainage capacity.Taking the renovation of Wangchuanchang waterlogged area of Hebei District of Tianjin as an example,this paper introduces the engineering design scheme in detail,and evaluates the hydraulic conditions of the drainage system and the regional waterlogging risks by using the InfoWorks ICM hydraulic model.The results show that the upgraded and reconstructed rainwater drainage system can ensure that basically no waterlogging in t he return period of 3 years.Although some pipelines are still overloaded,the water levels are below the ground elevation,basically meeting the requirements of rainwater discharge.In the return period of 100 years,the flooding and waterlogging scope and depth,and water receding time in the region are significantly reduced.The reasonable solutions for the problems encountered in the design can provide references for similar upgrading and reconstructing designs of the drainage systems in the central urban waterlogged areas.
