| 摘 要： | 提出一种基于面向对象的方法,以元件的对象属性表达管网的拓扑结构,以对象方法表达水力计算模型,用对象事件反映边界条件变化响应的方法,然后通过遍历整个管网元件对象进行水力计算.对工程中两种常见的多源管网结构进行计算,分析表明,新方法能有效地处理多源环状管网结构、源变化引发的水力平衡问题,计算偏差小,能够充分满足工程计算的需求.

| Abstract: | An algorithm based on object-oriented(OO) method is proposed.All pipe components in network topology structure are given special object properties.Hydraulic calculation models are expressed by object methods.Boundary conditions variations are reflected by object events.Then hydraulic calculation can be solved as traversing all pipe components.Two cases are calculated and analyzed.It indicates that the method can effectively handle hydraulic imbalance caused in structure or in heat sources of a multi-source looped-pipe network with small deviations. |

| Keywords: | loop pipeline network multiple sources hydraulic computation object oriented |
