摘要
在城市雨水利用中,雨水调蓄容积的计算依其目的、方式、有无渗透、溢流做法等条件的差异而不尽相同。主要从城市雨水利用的角度出发对雨水调蓄的不同方式及其调蓄容积计算原理进行了评述,并对其实用算法进行探讨和分析,主要包括降雨量估算法、降雨强度曲线计算法、统计降雨频率累计法。对有削减洪峰要求的调蓄储存池建议核算其削峰容积。结合实际,对雨水调蓄的泥区容积、超高和溢流方法也进行了讨论。
In referring on the regulation and reservation volume for urban rainwater utilization some factors such as the aim, the manner, the infiltration and spill in utilization should be taken into consideration and different calculation methods have to be used to meet the particular situation. In this paper the rainwater regulation and reservation manners are reviewed and some practical calculations of regulation volume, namely the precipitation capacity estimation, precipitation intensity curve computing and statistic precipitation frequency accumulation methods are discussed. For a regulation-reservation tank if the peak clipping is required, the calculating result has to be checked by the peak clipping volume. Other problems, including the sludge volume, dry board and spilling installations of the regulation tank are discussed as well.
