- 摘要:
- 以北京市某新建区域的雨水系统为例，利用InfoWorks ICM水力评估软件建立区域地块及周边市政设施的一维雨水系统模型，对区域开发前后的雨水外排量及其排入的市政管线运行情况进行模拟分析。为使地块开发后外排雨水量满足建设区外排水量的要求，以及不对其排入的市政管网运行造成影响，借鉴海绵城市建设理念，提出了几种雨水排除及调蓄的低影响开发方案，并进行综合分析比较，得出可行的区域建设方案。结果表明，下凹式绿地、透水路面等“绿色”低影响开发措施可削峰，“灰色”调蓄池既可削峰又可错峰，且相同容积下离线调蓄池的运行效果较在线调蓄池更优，结合项目实际情况进行“灰”“绿”结合更有利于控制雨水外排。该研究提供了一种区域雨水外排评估方法及低影响开发措施在区域中实施的思路。
- Abstract:
- A one-dimensional pipe network system model of a newly built regional rainwater system and surrounding municipal facilities in Beijing was established by using hydraulic evaluation software of InfoWorks ICM,and the discharge amount of rainwater and the operation of the receiving municipal pipeline before and after regional development were simulated.In order to make the drainage amount of rainwater after development meet the requirements and not affect the operation of the municipal pipe network, several low impact development schemes of rainwater drainage, regulation and storage were proposed based on the construction concept of sponge city, and feasible regional construction schemes were obtained through comprehensive analysis and comparison. Green lowimpact development measures like sunken lawn and permeable pavement could cut the peak flow.Gray storage tank could cut and delay the peak flow, and the off-line storage tank with the same volume had a better operational performance than that of the online storage tank. Therefore, the combination of gray and green measures based on the actual situation of the project was more conducive to the control of rainwater drainage. The study provides an evaluation method of regional rainwater discharge and an idea of implementing low impact development measures in regional development.
