摘　　要：基于排水数值模型提出一种雨水管网改造新方法,该方法以管道排水能力等级图为导向,并结合水力坡降和问题管道纵断面分析内涝具体成因,从而进行针对性、系统性管网改造,以缓解小区级别易涝片区的内涝问题。以深圳市矮岭片区和马峦创谷片区为例,来验证片区雨水管网改造方法的可行性和有效性。结果表明,片区雨水管网改造方法对区域内涝缓解有较为明显的效果,矮岭片区和马峦创谷片区内超Ⅲ级的管道均转为安全和较安全状态,最终能达到10年一遇降雨下无积水的目标。A new method of rainwater pipe network reconstruction is proposed based on the drainage numerical model in this paper. The method is guided by the pipeline drainage capacity grade map, and combines the hydraulic slope and the longitudinal section of the problematic pipeline to analyze the specific causes of waterlogging, so as to carry out targeted and systematic pipeline network. Renovation to alleviate the waterlogging problem in the flood-prone areas at the community level. Taking the Ailing area and Maluan Chuanggu area of Shenzhen as examples to verify the feasibility and effectiveness of the reconstruction method of the rainwater pipe network in the area. The results show that the reconstruction method of the rainwater pipe network in the area has a relatively obvious effect on the mitigation of regional waterlogging. The pipelines in the Ailing area and the Maluanchuanggu area are all turned into a safe and relatively safe state, and can finally achieve 10 year rainfall. target without waterlogging.
