摘要
环状网初分流量方法中 ,比较适用的是改进的最小平方和法 ,即考虑管长因素的最小平方和法。而管长幂次数的不同对分配结果影响颇大。采用计高幂次管长的最小平方和法分配管网初始流量 ,加重了管长因素对流量的影响 ,并使结果更符合流量分配原则。文章通过对不同幂次数计算结果的分析、比较 ,提出较合理的取值 ,并在算例中得到验证。
Among the initiatory flow distribution methods of looped network, the improved method of minimum square summation is a suitable method for it considers the pipe length. But the different indexes of pipe length generate different results. However, when the larger indexes of pipe length are counted in distributing the initiatory flow of pipe network with the method of minimum square summation, the pipe length's influence on the flow can be considered fully,and the results are more rational according to the principles of flow distribution. In this paper, a reasonable index value is obtained by comparing with different results, and this value is testified in an example.
