摘　　要：为考察拟建工程对暴雨天气的抵抗能力,以武汉市右岸大道(江安路-八坦路)工程为例,采用InfoWorks对其排水设计方案进行了内涝风险预评估。为解决右岸大道内涝问题,建议:按规划同步打通下游雨水通道,并在此基础上增加抽排泵站,以加强末端出路的排水能力;在内涝风险较高的路段加密雨水口布置,并改用边沟收水,以提高路面雨水的收集效能;做好市政雨水管网的维护工作,以减轻管道及路面收水设施的淤积。此外,对雨水口布置间距、边沟尺寸和泵站规模进行了模拟分析。该预评估方法及优化建议可为其他同类工程提供借鉴。This paper pre‑assessed the waterlogging risk of You’an Avenue(Jiang’an Road to Batan Road,Wuhan)drainage design project via InfoWorks,so as to investigate the resistance of the proposed project to rainstorm weather.The following suggestions were proposed to solve the waterlogging problem in You’an Avenue.Firstly,the stormwater drainage channel located downstream shall be constructed simultaneously according to the plan,and the pumping station shall be built on this basis to enhance the drainage capacity of the end outlet.Secondly,the stormwater inlet in the sections with higher waterlogging risk shall be densified and replaced by side ditch to collect runoff,so as to improve the runoff collection efficiency of road.Thirdly,good maintenance of the municipal stormwater pipe network is runoff conducive to reducing the siltation of pipeline and road runoff collecting facilities.In addition,the arrangement space of stormwater inlet,the size of side ditch and the scale of pumping station were simulated.The pre‑assessment method and optimization suggestions aim to provide reference for other similar projects.
