摘　　要：在厦门市主城区部分建筑与小区排水管网进行溯源排查,根据排查结果对目前排水管网缺陷情况进行评估分析。排查结果显示,研究范围内排水管网总长26.3km,约有27.7%的排水管段存在缺陷,管道缺陷以破裂和变形为主。利用SWMM模拟软件模拟管网存在缺陷及不同修复方案下的运行情况,模拟结果得出,至少同时修复Ⅳ级缺陷和Ⅲ级缺陷对恢复排水管网运行能力有较好的效果。Through the investigation of the drainage pipe network of some buildings and communities of Xiamen,the current drainage pipe network defects are evaluated based on the investigation results.The investigation results show that the total length of the drainage pipe network in the study area is 26.3km,and about 27.7%of the drainage pipe sections have defects,mainly cracks and deformations.Combining the results of pipeline evaluation,SWMM simulation software is used to simulate the existing defects of the pipeline network and the operation of different repair schemes.The simulation results show that repairing at least the IV defects and the III defects at the same time has a good effect on restoring the operation capacity of the drainage network.
