摘要:
在城市化的大背景下,针对天津市暴雨洪水的特性,通过建立天津市中心城区及环城四区的SWMM模型并对其进行了率定验证,计算了不同重现期设计暴雨下的降雨径流,对比了城市实际排水管网能力。结果表明,城市现状排水管网排水能力不足,大部分地区遭遇强降雨时形成的径流过程超出了控制泵站的排水能力。针对这一情况,设计利用低影响开发措施(LID)中的生物滞留区与透水铺装措施来控制洪峰及径流总量。结果表明,LID控制措施能有效削减洪峰及径流总量达40%,但随着所遭遇设计暴雨重现期的增大,削减效果有所下降。
Abstract:
In the context of urbanization,according to the characteristics of rainstorm flood in Tianjin,SWMM model of Tianjin city proper and its surrounding four districts was established and validated to calculate rainfall-runoff under different return periods of design rainstorm. Compared with the actual drainage pipe network capacity,the results show that the current urban actual drainage pipe network capacity is insufficient. The runoff in most of the areas under heavy rainfall exceeds the controlling pump station drainage capacity. In view of this situation,low impact development measures (LID) of SWMM such as bio-retention facilities and permeable pavement were designed to control the flood peak and total runoff. The results show that the LID control could effectively reduce the flood peak and total runoff by 40%.But with the increase of the return periods of the design Rainstorm,the reduction effect is decreased.
