摘　　要：遭受暴雨与内涝的侵袭和困扰,是我国城镇在经济发展过程中遇到的普遍问题,在广州地区表现尤为突出。基于暴雨强度公式,应用芝加哥降雨过程线对广州市在不同重现期暴雨进行时程分配,得到1~50a5种典型暴雨重现期的设计降雨过程。采用SWMM模型,选取广州市一典型移民新村作为研究对象,将其排水系统进行概化,模拟在实际暴雨情景下入水口流量、节点积水和管渠满载情况,并与实际监测数据对比,以验证模拟的准确性。模拟不同重现期设计暴雨过程研究区内涝情景,考察不同暴雨强度下内涝点数量、积水程度和管网负荷,以探寻研究区域内涝的限制性因素,并基于此提出内涝控制措施。Undergoing rainstorms and waterlogging is a common problem for China＇s townships in the process of economic development,especially in Guangzhou＇s economic development.Based on the storm intensity equation,the rainfall distributions in the 1~50a return periods are studied by using the Chicago rainfall process line.A typical township in Guangzhou is selected as the study object to generalize the drainage system by using SWMM.The flow and the water depth is simulated in the actual rainfall,and compared with the monitoring data,which is applied to verify the accuracy of the simulation.The waterlogging of the town in five design storms of different return periods is simulated.The waterlogging points,the water depth and the pipe load are studied to explore the limited factors of waterlogging in the research area.Finally,the suggested flood control measures are presented based on the causal analysis of waterlogging.
