COMPARIATIVE STUDY BETWEEN PLANE STRAIN OBSERVED DATA WITH YRY-4-TYPE COMPONENT BOREHOLE STRAINMETERAND TJ-2-TYPE VOLUMETRIC BOREHOLE STRAINMETER
两种应变仪的面应变观测资料的比对研究

During the tenth five-year plan,a set of YRY-4-type componenet borehole strainmeter and a set of TJ-2-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 inf...
