摘　　要：为量化评估低影响开发(LID)设施及其组合在市政道路中的雨洪控制效果,基于SWMM模型构建武汉市典型3幅式海绵道路雨洪模型,模拟评估了传统道路和下凹式绿地、透水人行道、透水路面单独布设及组合布设等8种方案在不同暴雨重现期(2年、10年及100年一遇)下水量控制效果。研究发现,单独设置下凹式绿地、透水人行道、透水路面,峰值消减率分别为12.16%~20.35%、4.54%~15.20%、0.83%~4.63%,出流量消减率分别为14.26%~27.48%、4.19%~8.66%、0.85%~1.95%;组合设置下凹式绿地+透水人行道、透水人行道+透水路面、透水路面+下凹式绿地、下凹式绿地+透水人行道+透水路面峰值消减率分别为25.34%~33.79%、11.07%~23.61%、10.48%~22.11%、25.30%~34.90%,出流量消减率分别为14.99%~26.69%、0.91%~1.61%、14.63%~28.34%、15.85%~28.32%。In order to quantify the flood control effect of LID facilities and their combination in the urban roads,a model by LID for Wuhan city sponge road is established based on SWMM model.The water quantity control effect of eight schemes are simulated and evaluated under single layout and combined layout of the conventional road,the independent sunken greenbelt,permeable walkway,permeable pavement respectively under different rainstorm return period(2,10 and 100 years).The study results indicate that only construction of sunken greenbelt,permeable walkway,or permeable pavement can respectively causes a reduction of 12.16% ~20.35%,4.54% ~15.20%,0.83% ~4.63% in peak discharge,and a reduction of 14.26%~27.48%,4.19%~8.66%,0.85%~1.95%in runoff volume.The combined sunken greenbelt + permeable walkway,permeable walkway + permeable pavement,permeable pavement+sunken greenbelt,sunken greenbelt+permeable walkway+permeable pavement can make a reduction of 25.34%~33.79%,11.07%~23.61%,10.48%~22.11%,25.30%~34.90%in peak discharge,and a reduction of 14.99%~26.69%,0.91%~1.61%,14.63%~28.34%,15.85%~28.32%in runoff volume.
