摘要
某高校校园存在地形起伏、局部区域不透水面积较大、排水管线埋设时间较长等特点,在排水不畅的情况下,高校校园内涝是城市内涝的重要组成部分。首先讨论内涝分析步骤,然后以某高校校园为案例进行了模拟和分析。通过构建高校校园内涝计算模型,模拟不同降雨重现期情景下的地表径流、节点积水和管道超载情况,从而分析造成高校校园内涝的主要原因并提出内涝防治意见。
One certain university campus has a rugged landform, large impervious area in partial regions and drainage pipes buried for a long time. Under the condition of poor drainage, campus waterlogging is an important part of urban waterlogging problems. Firstly, the steps of waterlogging analysis are discussed. Then a university campus is used as a case for simulation and analysis. By constructing the calculation model of campus waterlogging,it is possible to simulate the condition of surface runoff,ponding nodes and overloaded pipes under rainfall with different return periods, which contributes to analyze the main causes of campus waterlogging and put forwardopinions on the prevention and control of waterlogging.
