【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。
[Abstract]:Torrential rain and waterlogging are the common problems in the economic development of cities and towns in China, especially in Guangzhou. Based on the formula of rainstorm intensity, the rainfall process line of Chicago is used to distribute the rainstorm of Guangzhou in different recurrence periods, and the design rainfall process of typical rainstorm recurrence period of 1~50a5 is obtained. By using SWMM model, a typical immigrant village in Guangzhou is selected as the research object, and its drainage system is generalized to simulate the inflow discharge, node water accumulation and full load of pipes and canals under the actual rainstorm scenario, and to compare with the actual monitoring data. To verify the accuracy of the simulation. In order to explore the restrictive factors of waterlogging in the study area, the number of waterlogging points, the degree of water accumulation and the load of pipe network under different rainstorm intensity were investigated by simulating the waterlogging scenarios in the study area during different recurrence periods, and based on this, the waterlogging control measures were put forward.
