| 摘 要： | 根据埋地管线水力瞬变探堵的基本原理,建立了埋地管道堵塞检测过程中的非稳态管流数学模型,同时对不同堵塞长度、不同管径等情形进行模拟计算和分析,得到全线压力和流量的变化.通过计算得知,沿着管线在适当地点布置少量的传感器,便可以快速预测堵塞位置.

| Abstract: | In this paper the theoretical basis of using hydraulic transient to detect the underground-tunnel's blockage is explored,and a mathematic model on the unstable runoff during the process of the check of the underground-tunnel's blockage is constructed.This model can also conduct analogue computation and analysis on different blockage length and tunnels of different types simultaneously and get the data of the changes of the pressure and the runoff of the whole tunnel.The computation results show that a few sensors set at the proper places along the underground-tunnel can locate the position of blockage promptly. |
