摘要
在满管流或水面平接非满管流多管段排水管网中,各管段在交汇节点上的水位高程相等,可以归纳为能量连续的排水设计管段。以最小工程造价为目标函数,充分利用设计管网起端至终点之间可利用最大水位差为输水能量,以设计规范规定为约束条件,建立排水管网优化设计坡度数学模型,求解各管段的经济坡度和优化管径。
In drainage system with full or partially full flows, the water levels at each junction are equal, which can be classified as continuous energy flows, a mathematical model for optimizing the slopes of pipelines was established, by using the minimum construction cost of pipelines as an objective function and the maximum available water level difference as energy for water flows. Providing the criterion of design is known, the economical slopes and optimal diameters of pipelines can be obtained from the solution of the mathematical model.
