供水管网的节点用水量和水损系数具有明显的不确定性，为研究节点用水量和水损系数的不确定性对供水管网水力特性的影响，提出了在假定他们的随机变化服从正态分布的条件下，采用蒙特卡罗随机抽样法，对所获的每组节点用水量和水损系数的抽样值，应用稳态的水力模型计算相应的节点测压管水头和管段流量，得出节点测压管水头和管段流量的统计值的计算方法。文中给出了该算法在两管网中的应用。

Node water demand and water loss coefficient water supply pipe network possesses obvious un -certain.In order to analyze the influence of node water demand and uncertainty of water loss coefficient on hydraulic characteristics of water supply pipe network ,the paper assumed that their random change o-bey the normal distribution condition of their normal distribution condition ,and took Monte Carlo sampling method to get the values of node water demand and water loss coefficient .It applied steady -state hydrau-lic model to calculate corresponding water head of node pressure tube and pipe flow .At last the paper pro-posed the calculation method of statistical value of node pressure tube water head and pipe flow which is applied in two pipe network system .
