【摘要】 给水管网系统优化设计是解决城市供水管道故障有效方法之一,通过将给水管网年折算费目标函数对管径的非线性函数作线性处理,从而建立了每一段管网的造价折算模型,并以表征给水管网特征的坐标参数作为约束条件,计算出线性规划最优解,且对管段能量方程作线性处理,在水力学动态平衡原理和有限元理论基础上,建立有限元分析模型。该计算模型实用简便,可为工程应用提供参考。更多还原

【Abstract】 The optimization design of the water supply network system is one of the effective ways to solve the malfunction of the urban water supply pipe.This paper processes water supply pipe net conversion fee objective function,for linear,establishes a conversion cost model for each segment of the network,uses the coordinate parameters of the water supply network parameters as constraints,calculates the optimal solution of linear programming,handles the pipe energy equation for linear,is based on the dynamic balance pipe finite element equations and hydraulic dynamic balance principle and the finite element theory,finally puts forward the dynamic balance pipe finite element analysis model,which serves as a referenced for the application of projects.更多还原
