城市雨水系统调蓄容积计算方法研究

Research of the calculation methods of storage capacity in urban rainwater system

分析了城市雨水利用设计中的月水量平衡分析法、年水量平衡分析法、最高日水量法等雨水调蓄容积计算方法存在的问题,提出了日水量平衡分析法,并进行了对比分析。结果显示,日水量平衡分析方法最符合雨水利用实际情况,应将其作为调蓄容积计算的主要方法。

Based on the analysis of rainwater storage capacity calculation methods,such as monthly water balance analysis,yearly water balance analysis and the maximum daily water amount analysis,there are some problems not solved in urban rainwater utilization system.This paper proposes the daily water balance analysis and analyzes the above methods.The results show that daily water balance analysis is the most consistent with rainfall and water consumption character, which should be the main method in storage capacity calculation.
