【摘要】 供水管网水力计算的理论和方法经历七十年的发展,已经相当成熟,但在应用中往往遇到基础数据准备和数据更新上的困难。将地理信息系统应用于水力计算,可以使水力计算中的大部分输入数据直接从GIS数据库中提取,并借助GIS的数据更新手段保持管网计算模型的现势性,还可以利用GIS的表现能力显示输出计算结果。本文讨论水力计算与GIS的集成方法,并提出了模型网络生成算法和流量归结算法。更多还原

【Abstract】 The theories and means of water supply pipe network hydraulic calculation are very mature through the progress of the past seventy years. But in practice people often find many difficulties in preparing and updating of basic data. By applying geographic information system to hydraulic calculation, a majority of input data can be picked up directly from GIS database. By dint of data updating capability of GIS, pipe network calculation model can keep up-to-date. Calculation results can be output by representing ability of GIS. This paper discusses the integration of hydraulic calculation and GIS, and then brings up the model network creation algorithm and the flux induction algorithm.更多还原
