摘　　要：对市政排水系统采取科学合理的优化措施可以有效提高系统的耐用性及排水效率。该文以暴雨积水的实际案例为例,对其影响因素进行总结分析,并提出相应的优化措施。基于不同的优化措施的对比得出,在单方案对比中,调蓄池对径流总量和溢流总量的的控制效果最佳,且当重现期p≥2时,4种措施对溢流总量的控制效果随重现期的增加呈现先增加后减小的趋势。在组合方案对比中,4种组合方案对径流总量的控制效果随着重现期的增加而减小,且方案二和方案四的效果优于方案一和方案三;对溢流总量的控制效果上,结合消减率的变化特点,方案四对溢流总量控制效果最好。Taking scientific and reasonable optimization measures for municipal drainage systems can effectively improve the durability and drainage efficiency of the system.This paper takes the actual case of heavy rain and water accumulation as an example to summarize and analyze its influencing factors and propose corresponding optimization measures.Based on the comparison of different optimization measures,it is concluded that in the comparison of single schemes,the control effect of the regulation and storage tank on the total amount of runoff and overflow is the best,and when the return period p≥2,the control effects of the four measures on the total amount of overflow show a trend of increasing first and then decreasing with the increase of the return period;in the comparison of combined schemes,the control effects of the four combination schemes on the total amount of runoff decrease with the increase of the return period,and the effects of Scheme 2 and Scheme 4 are better than Scheme 1 and Scheme 3;in terms of the control effect of the total overflow amount,based on the changing characteristics of the reduction rate,the fourth option has the best effect on the total overflow amount control.
