Application of RZB Borehole Strainmeter in Crustal Stress Monitoring

Abstract

This paper introduces RZB component-type borehole strainmeter and features used for continuous observation of crustal stress-strain and conducts a preliminary analysis of observational data of the RZB component-type borehole strainmeter in the crustal stress monitoring station at Renhe Station, Panzhihua City of Sichuan Province. The result shows that: the RZB component-type borehole strainmeter in the crustal stress monitoring station at Renhe Station, Panzhihua City of Sichuan Province has a higher resolution ratio, which can not only record clear solid tides, but also record broadband strain seismic waves. It reflects the broadband characteristics of RZB component-type borehole strainmeter, which greatly enriches the observational data of borehole strain and provides abundant data and basis for seismic research.
