Study on Trend-surface Analysis Model for Pressure in Water Supply Network and Its Application

从供水管网的压力分布特性出发,提出了运用趋势面分析法建立供水管网压力趋势面模型的可行性,讨论了模型求解的步骤,并用实例对模型进行了验证。结果表明,该模型能够真正实现管网压力的连续性模拟,为解决城市供水管理和调度系统中管网压力模拟提供了一个新方法,增强了决策的科学性和准确性。

The node pressures of network which are discrete data can build a continuous pressure surface by trend-surface analysis to demonstrate the change trend of pressures of network in different zones. Based on the distribution of pressure in water supply network, this paper puts forward the feasibility of using trend-surface analysis to set up the trend-surface model of pressure in water supply network, discusses approaches of solving the model that has been validated by an example. The result indicated that the model can really carry out the continuous simulation of pressure in network, and provide a new method to resolve technical puzzles of the pressure simulation of network in urban water supply and operation system, and enhance the rationality and veracity of strategy.
