摘要
目前,在水利水电工程灌浆施工中,地表抬动监测主要用千分表等,千分表观测存在灵敏度受环境影响大,不能连续观测等问题。通过对光栅传感器进行特性分析,证实了其应用于地表抬动监测是可行的,并提出了光栅传感器与灌浆自动记录仪结合的方案,研制了一套新的地层抬动监测系统,可实现抬动测量自动化,可确保测量精度及连续性。
At present, in the grouting construction of water resources and hydropower projects, the stratum lift-movement is monitored by dial gauge. But the observation sensitivity of dial gauge is affected greatly by the environment and could not continuously observe. The characteristic analysis of grating sensor shows that it is feasible to apply in the stratum lift-movement monitoring. This paper also puts forward the alternative of combining the grating sensor with automatic grouting recorder and develops a new stratum lift-movement monitoring system, which can realize the lift-movement measurement automation and guarantee measurement accuracy and continuity.
