配水网络在城市给水系统中占有重要的地位,深入研究配水网络的分析计算方法,对于经济、合理的设计和管理都有重要意义。配水网络的分析主要包括系统的水力学平衡计算(管网平差)与网络的优化设计计算。1936年,Hardy Cross提出的解环方程的管网平差方法目前仍在普遍应用。求解环方程的方法比较复杂,对于不同的结构形式的网络,需采用不同的计算过程,且对于某些问题未必能获得收敛解。网络优化设计的合理方法,目前仍是一个值得探讨的课
Water distribution network occupies an important position in the urban water supply system. In-depth study of the analysis and calculation method of distribution network is of great significance for economical and reasonable design and management. The analysis of the water distribution network mainly includes the calculation of the hydraulic balance of the system (pipe network adjustment) and the optimization design of the network. In 1936, the pipe network adjustment method proposed by Hardy Cross to solve the ring equation is still widely used. The method for solving the ring equation is more complicated. Different networks need different calculation processes for different structural forms of network, and for some problems, it may not be possible to obtain a convergent solution. The reasonable method of network optimization design is still a class worth exploring.
