水力模型在大落差重力流供水规划中的应用

Application of Hydraulic Model in High Drop Height and Gravity Flow Water Supply Planning

以西南地区A市供水专项规划为应用实例,阐述了水力模型在山区地形多水源供水规划中的几点关键应用。传统设计方法中对于大落差、重力流、多水源等特点的供水规划存在诸多难点,利用水力模型进行辅助设计,对现状管网进行评估分析、供水区块划分、管网压力管控、对置水塔水位确定和动态分析以及特殊工况的模拟校核等。水力模型的应用较好地实现了上述分析效果,为供水规划设计提供了科学依据。

Taking the water supply planning of city A in southwest China as an example, several key applications of hydraulic models in water supply planning for mountainous regions were described. Traditional design methods encounter challenges such as high drop height, gravity flow and muhiple water resources. Hydraulic models were utilized to evaluate the status of pipeline network, delineate water supply zones, control pressures, determine water levels in water towers, and simulate special scenarios. The application of hydraulic model provided analysis results as well as scientific bases for water supply planning design.
