基于GIS的给水管网动态水力计算模型的建立与应用

Establishment and implication of GIS based dynamic hydraulic calculation model for water supply network

基于GIS和给水管网水力计算方法,采用一种新的更符合实际的节点流量分配方法,建立了给水管网动态水力计算模型,实现了模拟结果和GIS图形信息的良好结合,解决了工况结果难以在GIS中显示和输出的问题。将模型应用于天津市津南区咸水沽镇供水管网,并将计算结果与MIKENET模拟值、EPANET2.0计算值进行比较,验证了模型的实用性。

In this paper a new and practical method for the allocation of node flow and to establish a GIS based dynamic hydraulic model for hydraulic calculation of water supply network were presented, The model works well with combination between simulated results and GIS graphical information as well as the display and output of the state results in GIS, which was hard to solve before, This model has been applied practically in the water supply network of Xianshuigu Town in Tianjin City, The practicability of the dynamic model was tested and verified by comparing the calculated values with the simulated values of MIKE NET and calculation values of EPANET2. 0. Finally, the application provided a new method for the establishment of a dynamic hydraulic model.
