摘　　要：水力计算模型是供水系统网络分析的一个重要因素,本文介绍了水力计算中水头损失、沿程流量等计算模型,研究了GeoDatabase数据模型的几何网络,并基于ARCGIS建立了矿山供水系统的几何网络,利用GIS强大的分析功能和可视化的特点,根据实际需求对矿山供水网络进行相应的网络分析,从而使供水网络分析及管理工作简便快捷。Hydraulic calculation model is an important part of the water supply system. This paper described the models of hydrau- lic calculation, Such as waterhead loss and the flow of water, studied the geometric network of GeoDatabasc data model and estab- lished the geometric network of mine water supply system based on ARCGIS. At last, according to the actual need, it conducted net- work analysis on the mine water supply network taking full advantage of the powerful analytic function of GIS and visualization charae- teristics, which made the analysis and management of water supply network easier and faster.
