浅谈振弦式应变计在北排河挡潮闸监测中的应用

Application of Vibrating Wire Strain Gauge in Monitoring the Tidal Gate at the Beipai River

在水工建筑物或其它混凝土建筑物内,测量结构物内部的应变量时,振弦式应变计是一种适于长期埋设并可同步监测埋设位置温度的测量设备。文中以天津市滨海新区新马棚口村东南北排河入海口处挡潮闸建筑物振弦应变计为例,详细介绍了应变计的工作原理、安装步骤及使用注意事项等,为类似工程中应变测量提供参考依据。

Vibrating wire strain gauge is a kind of monitoring instrument suitble for longterm burial and synchronous measurement of burial point temperature,when we monitor the internal stress and strain in hydraulic buildings and other concrete buildings.Combining with the vibrating wire strain gauge in the building of tidal gate at mouth area of the Beipai River,in the southeast of Xinmapeng Village,Binhai New District,Tianjin,this paper introduces the working principle,installation procedure,and usage attention of vibrating wire strain gauge,which provides the reference for strain measurement in such engineerings.
