城市给水管网系统模型的校核

Calibration of Urban Water Distribution Network Model

对给水管网系统模型进行校核可提高其可信性和实用性,为此给出了模型校核的整体思路,在分析影响因素的基础上,提出了通过调整节点流量和海曾—威廉C值来减少变量个数的方案。算例表明该方法是可行的。

Calibration of water distribution network model can improve its credibility and practicality, therefore a whole idea on the model calibration is presented. A scheme in which number of variables is reduced by adjusting node flow and C value of Hazen - Williams formula is proposed based on the analysis of affecting factors. This approach is proved to be feasible by means of case calculation.
