摘　　要：以广州市国家综合管廊试点区域——杨梅河流域为研究对象,利用SWMM和SUSTAIN模型对传统开发情景、传统综合管廊情景、低影响开发情景、低影响开发和综合管廊联合作用的“海绵型”综合管廊情景下的水文效应进行对比评估,结果表明:实测降雨条件下,SWMM模型的模拟结果与流域内涝实际情况相符,证明该模型适用于杨梅河流域水文效应研究;结合SWMM和SUSTAIN模型的优势,将SUSTAIN模型中的低影响开发优化布局方案输入至SWMM模型进行水文模拟,使得低影响开发布局更科学合理;“海绵型”综合管廊情景下,溢流量削减效果最佳,50 a重现期设计降雨条件下溢流总量削减率超过60%,与“快排”模式下的传统综合管廊情景相比,“海绵型”综合管廊使杨梅河出水口峰值流量明显降低,峰现时间也相应延迟。The Yangmei River Basin,a national pilot area of integrated pipe corridors in Guangzhou City,was taken as the study area.The SWMM and SUSTAIN model were used to compare and evaluate hydrological effects under four scenarios,including the scenarios of traditional development,underground integrated pipe corridors(UIPC),low impact development(LID),and the combination of LID and UIPC(LID-UIPC).The results showed that,under the condition of measured rainfall,the simulated overflow point with the SWMM was in good agreement with the place prone to waterlogging in reality,proving that the SWMM was suitable for the hydrological effect evaluation in the Yangmei River Basin;combining the advantages of the SWMM and SUSTAIN model,the LID layout optimization schemes calculated by the SUSTAIN model were input into the SWMM for hydrological simulation,resulting in more reasonable LID layout;the overflow reduction rate under the LID-UIPC scenario was the highest,which exceeded 60% under the condition of a 50-year return period rainfall,its peak discharge at the outlet was lower than that under the UIPC scenario,and its peak appearance time was also delayed.
