在传统的排水管道设计中,雨、污水管道的水力计算是非常繁琐的。特别是当管网系统比较复杂时,管网的调整计算难度将加大。利用GIS组件MapObjects提供的GIS数据浏览、编辑和分析能力,通过管网水力计算模型提供管网计算功能,实现了从规划设计的平面布置图层自动生成整个管网的管道纵断图,并可在管道纵断图中交互式的进行管道埋深、坡度、管径等设计参数的调整,计算模型将自动验证这些参数调整是否可行、是否影响上下游管道的设计参数,并进行相应的计算。
In traditional drainage design, the hydraulic calculation of rain and sewer pipes is very tedious. Especially when the pipe network system is more complicated, it will be more difficult to adjust and calculate the pipe network. The GIS data browsing, editing and analyzing ability provided by GIS component MapObjects is used to provide the pipe network calculation function through the pipe network hydraulic calculation model, and the pipeline longitudinal diagram of the pipe network is automatically generated from the plan layout layer. Adjusting the design parameters such as pipeline depth, slope and pipe diameter interactively in the pipeline longitudinal diagram, the calculation model will automatically verify whether the adjustment of these parameters is feasible or not and affect the design parameters of the upstream and downstream pipelines and make corresponding calculations.
