摘　　要：文中给出了利用图论中的回路法进行管网水力计算的解析表达式,得到了离散求解的递推关系式。在利用回路法和传统的Hardy Cross法对算例管网进行水力计算时,采用了不同的初始流量分配方案以研究其对收敛性的影响。计算结果表明初始流量分配对回路法的迭代次数影响很小,对Hardy Cross法的影响较大。The analytical formula is given for the hydraulic computation of the networks based on the loop method, and the discrete equation is deduced. With the loop method and the conventional Hardy Cross method, the paper investigated the effect of different initial discharge distribution on the astringency. The results indicate that the initial discharge distribution has less effect on the iterative degree of the loop method than that of Hardy Cross method.
