城镇供水水库调节计算方法的改进

Improvements for the Runoff Regulation Method of Urban Water Supply Reservoir

《水利工程水利计算规范》中缺少城镇供水水库径流调节计算的具体方法,并且工程设计中常用的调节计算方法存在一些问题。为解决这些问题,提出了改进的计算方法,避免了常规方法不合理的假设条件、简化计算等。改进方法采用长系列连续计算,进行全时段等流量调节,可以获得比常规方法更合理的供水过程和更大的保证供水量,提高水库供水调节的合理性。

Regulation for Water Conservancy Computation of Water Projects SL104---95 lacks the specific calculation method for reservoir runoff regulation of urban water supply and the common adjustment methods include a number of unreasonable problems. In order to solve the problems, the article pointed out improved methods to avoid the problems, like unreasonable postulated conditions of common methods, simplified calculation, etc. The improved method is long series of continuous calculating method to take constant mass flow control in each period. Compared with common methods, the improved calculation results can gain a more reasonable water supply process and more firm water supplies, and improve the rationality of＂ reservoir water supply regulation.
