| Abstract: | To investigate the reliability and stability of the RZB-type borehole strain sensor with the function of the range expansion and in-situ calibration,we design a qualitative comparison experiment of this sensor with conventional sensors under cave conditions,and quantify the daily drift of the sensor.The superiority of the RZB borehole strain gauge sensor is verified by plotting and analyzing the observed data from 2019-10 to 2020-05 and calculating statistics. |
