摘　　要：某水库工程长期处于涉水环境,受到高水头作用,坝体损坏严重,掌握坝体结构内部的渗流状态具有重要意义,利用测压管监测水库的渗流稳定显得尤其重要。测压管靠管中水柱的高度来表示渗透压力的大小,可用来监测坝体浸润线、渗压压力、地下水位及绕坝渗流等,广泛应用于水利、石油、化工、工程机械制造、煤矿等行业。阐述了测压管的埋设、灵敏度试验,对测压管水位进行观测,通过对浸润线的分析,判断水库的安全性。One of the major objectives of the reservoir project is to provide domestic and industrial water for Shiqiao Town,Zhawang Town and Zhawang Lingang industrial area of Ganyu County as well as considering the regional flood control and the farmland irrigation.The reservoir is in the water related environment for a long time,subjecting to the action of high-water head,the dam body is seriously damaged.It is of great significance to understand the seepage state inside the dam structure.Therefore,it is particularly important to monitor the seepage stability of reservoir by using the pressure measuring pipe.The pressure measuring pipe is an old and common seepage monitoring instrument,which depends on the height of the water column in the pipe to indicate the magnitude of the osmotic pressure.It can be used to monitor the seepage line,osmotic pressure,groundwater level and the seepage around the dam.This instrument is widely used in the water conservancy,petroleum,chem-ical industry,construction machinery manufacturing,coal mining and other industries.This paper describes the buried and sen-sitivity test of the pressure measuring pipe,observes the water level of the pressure measuring pipe,and judges the safety of the reservoir by analyzing the wetting line.
