摘　　要：为了有效解决城市内涝问题,需要对管道排水标准和河道排涝标准的合理衔接做进一步的探讨。破坏率分析法及相融性分析法都是现阶段管道排水标准与河道排涝标准衔接研究中较为常用的两种方法,选择江苏省宿迁市作为研究区域,运用这两种方法从河道顶托和平衡降雨强度两个角度对宿迁市排水与排涝的重现期衔接问题进行研究,发现两种重现期分析方法得到的衔接结果总体相近,仅在管道重现期为2 a的低重现期下有一定偏差。建议两种重现期分析法在实际运用中可以相互比对验证,为城市排水防涝系统的建设与完善提供科学参考。In order to solve urban waterlogging problems effectively, it is necessary to study further about the reasonable relationship of the pipe drainage and river drainage.The damage rate method and the coherence method are usually used in the study of the relationship between the pipes drainage and river drainage nowadays.Choosing Suqian city of Jiangsu Province as study area, we apply these two methods in the study area to discuss the relationship between the pipes drainage and river drainage considering the influence of river water level and the balance of rainfall intensity.Results made by these two methods are generally similar, but when the standard of the pipes drainage is two years which is a low recurrence period, there occurs certain deviation.This research recommends that these two methods could be references for each other in practical application and offers a scientific guidance to the further construction and improvement of the drainage and waterlogging system.
