振弦式渗压计埋设过程中容易被忽视的几个细节

渗压计是大坝渗流监测的主要设备之一.在长期工程实践中,渗压计的埋设方法已经比较成熟.但是,渗压计埋设过程中的高程修正、传感器及电缆固定方法、初始值的取值、接线以及配套材料的使用等问题往往被忽视,造成埋设成功率低下.以振弦式渗压计为例,通过分析以上问题的成因,提出了相应的解决办法.

Some Easily Ignored Aspects in Embedding Vibrating Wire Piezometers

Piezometers are the main instruments for seepage observation of dams.Based on the long-term engineering experiments,the embedment methods of the piezometers are relatively mature.But there are some factors to be easily neglected,such as elevation correction in embedding piezometers,fixing methods of sensors and cables,choice of the initial value,wiring details and utilization of supporting materials.They will cause the low survival rate of the embedment.Here taking the vibrating wire piezometers as an examp...
