| 摘 要： | 以江西省萍乡市某道路为研究对象,对研究区域进行概化、率定及验证后,运用SWMM模型模拟2、10、100 a一遇设计降雨条件下道路出口的径流过程,分析下凹式绿地、透水砖和透水路面3种典型海绵措施组合方案的雨洪控制效果。研究结果表明,在2、10、100 a一遇降雨条件下,洪峰流量削减率为0.20%~59.69%,径流总量削减率为12.69%~63.99%,洪峰迟滞时间为2~5 min。各海绵措施组合方案对降雨径流均具有削减和推迟作用,其中方案三的雨洪控制效果优于其他方案。

| Abstract: | Taking a road in Pingxiang City,Jiangxi Province as the research object,after generalizing,calibrating and validating the research area,the SWMM model is used to simulate the runoff process of road exit under designed rainfall conditions from 2 to 100 years,and the control effect of three typical sponge measures combination schemes,sunken lawn,permeable brick and permeable pavement are analyzed.The results show that under the rainfall conditions of 2 to 100 years,the peak flow reduction rate is 0.20%~59.69%,the total runoff reduction rate is 12.69%~63.99%,and the peak lag time is 2~5 min.The combination schemes of sponge measures can reduce and delay the rainfall runoff,and the rainwater control effect of scheme 3 is better than other schemes. |
