Abstract
Taking a road in Pingxiang City, Jiangxi Province as the research object, after generalizing, calibrating and validating the research area, the SWMM model was 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 were 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 2~5min. 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.
