摘　　要：针对某水乡城市的城市特色、水文气候及土壤地质等情况进行分析,并结合文化体育休闲公园的场地设计和排水系统设计,提出海绵设计方案。围绕年径流总量控制率80%、设计降雨32 mm的目标,将区域分为6个排水分区。对每个排水分区进行海绵设施布局,并通过容积法进行计算,最终确认设施规模,核算后年径流总量控制率达87%。根据暴雨洪水管理模型(SWMM模型)模拟结果,经过海绵设施建设,32 mm降雨条件下,管道雨水仅有少量出流,SS去除率达55%。The urban characteristics,hydrological climate and soil geology of a water town city are analyzed,and a sponge design scheme is proposed combined with the site design and drainage system design of a cultural,sports and leisure park.According to the goal of 80%annual runoff control rate and a 32 mm designed rainfall,the area is divided into 6 drainage zones.The sponge facilities are arranged for each drainage zone,and are calculated by the volume method.Finally the scale of the facilities is confirmed.After accounting,the total annual runoff control rate will be reached 87%.Based on the simulation results of the storm water management model(SWMM),after the construction of sponge facilities and under the condition of 32 mm rainfall,only a small amount of rainwater is coming out of the pipelines and the SS removal rate reaches 55%.
