Abstract:This paper compares the observation data of different borehole strain meters of Taian fiducial seismic station. We analyze the self-testing reliability of component borehole strain. The correlation of component borehole strain meter and volume strain meter in the normal state and during drawing water conditions is also studied. The correlation coefficient between S1+S3 and S2+S4, two orthometric components of RZB-3, is 0.999 9. The correlation coefficient between S1+S3 and S2+S4 of RZB-3 and volume strain is above 0.998. However, there is poor correlation when the instruments are disturbed by pumping.
