Abstract During the tenth fiveyear plan, a set of YRY4type componenet borehole strainmeter and a set of TJ2 type volumetric borehole strainmeter were installed in Xuzhou seismostation.At present the observed original plane strain curves from 2008 to 2010, the annual change of plane a systematic comparative study on strain curves, rainfall interference of plane strain curves, pressure interference of plane strain curves and the solid tidal observations is carried out and the respective correlation coefficient and influence coefficient are calcucated as well. This work has practical significance to demonstrate the reliability of the instrumentation, determine the credibility of the information and for correctly understanding of seismic background.
Key words ：
