%X On the basis of operating principle and the observations by borehole shear strainmeter and by use of theoretical earth tide,a new method for in-situ calibration of borehole shear strainmeter at Taian station is presented.The results show that the data of shear strain 2 are reliable because the component 2 and 4 of shear strainmeter work normally.The calibration coefficients of component 3 are considerably fluctuant.The data of shear strain 1 and 2 agree with their theoretical values on the whole after in-situ calibration.The shear strain observations have to be calibrated in different periods of specific issues,as the calibration coefficients change with time.
