Abstract Onthebasisofoperatingprincipleandtheobservationsbyboreholeshearstrainmeterandbyuseof theoreticalearthtide,anewmethodforinsitucalibrationofboreholeshearstrainmeteratTaianstationispresented.Theresultsshowthatthedataofshearstrain2arereliablebecausethecomponent2and4ofshearstrainmeter worknormally.Thecalibrationcoefficientsofcomponent3areconsiderablyfluctuant.Thedataofshearstrain1and 2agreewiththeirtheoreticalvaluesonthewholeafterinsitucalibration.Theshearstrainobservationshavetobe calibratedindifferentperiodsofspecificissues,asthecalibrationcoefficientschangewithtime.
