摘　　要：针对西安某现状雨水出口排水设计标准低、排水能力不足的问题进行分析,引出新建雨水出口调蓄池及防涝泵站的必要性,继而确定工程位置和布置形式;基于推理公式法、InfoWorks模拟法2种方法计算雨水设计流量,利用3种方法计算调蓄池容积,并通过InfoWorks软件模拟确定了3种调蓄池容积对应的泵站规模,通过方案比选分析确定“2.7万m3调蓄池+63 m3/s泵站”为该项目最优组合。通过泵站-调蓄池模拟运行流量过程线完整地模拟了一场暴雨过程,并运用CFD对调蓄池及防涝泵站的流态进行模拟。模拟结果显示,防涝泵站建成后区域排水能力将由9.6 m3/s提升至96.0 m3/s,暴雨重现期将由1.5 a提升至5 a;调蓄池建成后能有效地削减洪峰流量,最大限度地控制地表径流污染物排入河道。The problems of low standards of outlet drainage design and insufficient drainage capacity in a certain rainwater outlet in Xi'an are analyzed in this article.The necessity of building a new rainwater outlet reservoir and flood prevention pump station is introduced,and then the engineering location and layout form are determined;Based on the inference formula method and InfoWorks simulation method,the rainwater design flow is calculated.The storage tank volume are calculated by three methods,and the pump station scale corresponding to the three storage tank volumes are determined by InfoWorks software simulation.The reservoir of 27 000 m3and the flood control pump station scale of 63 m3/s are determined to be the optimal combination by scheme comparison and analysis.A rainstorm process is completely simulated through the pump station-resrevior simulation running flow hydrograph and the flow pattern is simulated by computational fluid dynamics(CFD).After the construction of the rainwater pump station,the drainage capacity of the area will increase from 9.6 m3/s to 96.0 m3/s.The return period of rainstorm increases from 1.5 a to 5 a;The regulating reservoir can effectively reduce the peak flow rate and maximize the control of surface runoff pollutants discharged into the river.
