摘要
以华北某景观河为研究对象,构建了基于InfoWorks CS的景观河道雨水系统模型。根据该区域汛期实测暴雨事件,对该景观河道现状雨水系统的运行进行了评估,发现大暴雨时现状雨水系统漫溢严重。在原模型和降雨事件的基础上,对提前排泄河道存水、降低河道初始水位、改变雨水泵站的开启和关闭水位、减小水闸高度等多种调度方案进行了模拟,得到了针对汛期暴雨较为科学的调度方法。最后对部分频繁漫溢的河道断面提出了新的雨水集水区分区建议。可为区域雨水系统优化和制定防洪排涝方案提供参考。
Taking a landscape river in North China as the research case, a rainwater system model of the city landscape river based on InfoWorks CS was constructed. According to a rainstorm event in flood season measured in the region, the operation of present rainwater system was evaluated, which was found that the present rainwater system has a serious flooding during heavy rain. Based on the original model and rainfall events, the case of draining water of the river in advance, reducing the initial level of the river, changing the opening and closing level of pumps, extending the width of the sluice were simulated, and the scientific scheduling method of rainstorm in flood season was obtained. Finally, for parts of the frequent over-flooding river section, the proposals of new rainwater catchment zoning were put forward. It could provide reference for regional rainwater system optimization and flood control plan decision.
