摘　　要：测压管——水库及大坝等水工建筑物的眼睛，用以观测地下水位、水温、水质等的动态变化规律。籍此资料可以测算渗透压力、温度应力以及水质对建筑物和基础的潜蚀或破坏的可能性，可以推测建筑物在使用过程中的稳定性。因而，它是一个非常重要的监测工具和手段。国内、外的水工建筑物几乎都埋设了测压管，并设有专门的机构对其进行长期观测。本文旨在利用北京密云水库第一溢洪道的测压管资料，来说明安全检查工作中发现的问题，即测压管水位偏高问题的研究方法和其对策。Piezometer tubes are the eyes of reservoirs、dams、and other hydraulic enginerring constructions,in order to observe the law of developments in groundwater level,water temperture,water quality etc.Use those data may measure and calculate osmotic pressure,temperature pressure and water quality,and then,it may be help us infer the possibility of scour piping or destroy,and infer the stability of constructions in apply process.Thorefore,it is a very importrant moniter instrument and method.In internal and external hydraulic engineering constructions,it seems ambushed Piezometer tubes,and set up special organization be in pregress long term observation. In this paper,for purpose of,to explain the find out problems in safe inspected work of Miyun Reservoir,even the problems of Piezometric level on the high side,study methods and its counter measures.
