摘要
探讨需水量不确定性及监测点布置对节点压力波动量的影响。采用蒙特卡洛模拟法,经算例计算得到需水量不确定性情况下的节点压力波动区间,并分析监测点数量与空间分布对节点压力的影响。结果表明:需水量不确定性与节点压力波动量呈正相关;压力监测点的合理布置有利于准确评估节点压力。
This paper discusses the influence about uncertainty of water demand and layout of monitoring points on nodal pressure fluctuation.By using Monte Carlo simulation method,the fluctuation interval of nodal pressure under the uncertainty of water demand is obtained by an example,and the influence of the number and spatial distribution of monitoring points on nodal pressure is analyzed.The results show that the uncertainty of water demand is positively correlated with the fluctuation of nodal pressure,and reasonable layout of monitoring points on nodal pressure is beneficial to the corresponding evaluation of nodal pressure.
