摘要
为评估西安小寨老城区海绵城市改造效果,采用耦合管网模块的二维城市雨洪模型对不同降雨重现期下小寨老城区海绵改造前后的内涝积水情况进行模拟。通过对比模拟不同降雨重现期下建设前后的积水分布、积水水量和积水面积,发现不同重现期下的内涝情况在海绵改造后均有所改善,小寨老城区海绵改造对老城区内涝缓解作用明显。
In order to evaluate the effect of sponge city reconstruction in Xiaozhai Old Urban Area of Xi’an,a 2 D urban storm flood model coupled with pipe network module was used to simulate the waterlogging situation before and after sponge city reconstruction in Xiaozhai Old Urban Area under different rainfall return periods.According to the comparison of the simulated distribution,volume and area of the waterlogging before and after the sponge reconstruction under different rainfall return periods,it is found that the waterlogging situation under each return period has been improved after the sponge reconstruction,and the sponge reconstruction has an obvious effect on the alleviation of waterlogging in the old urban area of Xi’an.
