摘　　要：为探究更为优化的环状给水管网流量分配方法,提出最小立方和流量分配法,并建立数学模型,采用步长加速法求解。对多水源管网进行了实例计算,在年费用、等水压线分布等方面,与最小平方和法作对比分析,结果表明,最小立方和法克服了最小平方和法的不足,流量分配更为合理。To explore more optimized method for flow distribution of looped water supply network, the method of mini- mum cubic summation is put forward, and the mathematical model that solved by step acceleration method was con- strutted. Through a case study of multi-source pipeline network, the annual costs and isopiestic lines distribution gained by the method of minimum cubic summation and the method of minimum square summation were analyzed, the results show that the method of minimum cubic summation overcomes some weakness of the method of minimum square summation and makes the flow distribution more reasonable.
