In order to explore the impact of river level and total rainfall duration on the drainage performance of rainwater pipe network, an integrated SWMM generalized model of pipe network and river in a certain industrial park was constructed. Based on the rainfall events with a return period of 5 years and the total rainfall duration of 2 h and 24 h, the drainage conditions of rainwater pipe network and river in industrial parks with different initial river levels were simulated and analyzed. The results show that when the initial river level is low and the outlet is free outflow, river level has little impact on the drainage performance of the rainwater pipe network. When the outlet is submerged, with the increase of the initial river level, the proportion of overloaded pipelines and overflow nodes in the drainage system increases, the overload time and overflow time are prolonged, the peak flow of outlets and pipeline nodes decreases, and the peak flow of node which is closer to outlet decreases more sharply. Based on the same rainfall return period and the initial river level, compared with the short duration rainfall, the proportion of overloaded pipelines and overflow nodes in the long-duration rainfall is larger, the overload time and overflow time are longer, and the peak flow of outlets and pipeline nodes decreases greatly. When designing the storm water drainage system with river-pipe network, it is advisable to check the drainage performance of storm water drainage system for 24 h rainfall and different river levels.

为探究河流水位及降雨总历时对雨水管网排水性能的影响,构建了某园区管网—河流一体化SWMM概化模型,基于设计重现期为5年、降雨总历时分别为2、24 h的降雨事件,模拟分析了不同河流初始水位时园区雨水管网和河流的排水工况。结果表明,当河流初始水位较低,排水口处于自由出流时,河流水位对雨水管网的排水性能几乎无影响。排水口淹没出流时,随着河流初始水位的提升,排水系统的超载管道比例和溢流节点比例递增,超载时间和溢流时间延长,排水口及管道节点峰值流量下降,且越靠近排水口节点峰值流量下降幅度越大;基于相同降雨重现期及河流初始水位,相比于短历时降雨,长历时降雨的超载管道比例和溢流节点比例较大,超载时间和溢流时间较长,排水口及管道节点峰值流量下降幅度较大。在进行河流—管网汇水区雨水排水系统设计时,宜对雨水排水系统进行历时24 h降雨、不同河流水位的排水性能校核。

为探究河流水位及降雨总历时对雨水管网排水性能的影响,构建了某园区管网—河流一体化SWMM概化模型,基于设计重现期为5年、降雨总历时分别为2、24 h的降雨事件,模拟分析了不同河流初始水位时园区雨水管网和河流的排水工况。结果表明,当河流初始水位较低,排水口处于自由出流时,河流水位对雨水管网的排水性能几乎无影响。排水口淹没出流时,随着河流初始水位的提升,排水系统的超载管道比例和溢流节点比例递增,超载时间和溢流时间延长,排水口及管道节点峰值流量下降,且越靠近排水口节点峰值流量下降幅度越大;基于相同降雨重现期及河流初始水位,相比于短历时降雨,长历时降雨的超载管道比例和溢流节点比例较大,超载时间和溢流时间较长,排水口及管道节点峰值流量下降幅度较大。在进行河流—管网汇水区雨水排水系统设计时,宜对雨水排水系统进行历时24 h降雨、不同河流水位的排水性能校核。

In order to explore the impact of river level and total rainfall duration on the drainage performance of rainwater pipe network, an integrated SWMM generalized model of pipe network and river in a certain industrial park was constructed. Based on the rainfall events with a return period of 5 years and the total rainfall duration of 2 h and 24 h, the drainage conditions of rainwater pipe network and river in industrial parks with different initial river levels were simulated and analyzed. The results show that when the initial river level is low and the outlet is free outflow, river level has little impact on the drainage performance of the rainwater pipe network. When the outlet is submerged, with the increase of the initial river level, the proportion of overloaded pipelines and overflow nodes in the drainage system increases, the overload time and overflow time are prolonged, the peak flow of outlets and pipeline nodes decreases, and the peak flow of node which is closer to outlet decreases more sharply. Based on the same rainfall return period and the initial river level, compared with the short duration rainfall, the proportion of overloaded pipelines and overflow nodes in the long-duration rainfall is larger, the overload time and overflow time are longer, and the peak flow of outlets and pipeline nodes decreases greatly. When designing the storm water drainage system with river-pipe network, it is advisable to check the drainage performance of storm water drainage system for 24 h rainfall and different river levels.
