 随着城市化进程的不断加快,供水管网和城市地形都在发生频繁的变化,管网简化模型必须随时更新,保持与现实管网的对应,才能使得水力计算的结果保持准确。将水力计算嵌入给水管网信息系统,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,绘制各种专题图。 更多还原

【Abstract】 With the progressive advancement of city,water pipes and terrain changed frequently.The pipeline simplified models must be updated at any moment to ensure the accurateness of hydraulic calculation results.By applying geographic information system to hydraulic calculation,a majority of input data can be picked up directly from GIS database.Depending on the data updating capability of GIS,pipe network calculation model can keep up-to-date.Calculation results can be output by representing ability o...
