中文摘要：

结合钻孔差应变仪的工作原理，借助体应变观测资料，提出了利用理论固体潮对泰安台差应变观测进行实地标定的新方法。通过对标定系数和滞后时间的分析认为：元件2、4工作状况比较稳定，观测值差应变2是比较可靠的；元件3的标定系数浮动较大。经过实地标定后，差应变1、2基本上与各自的理论值相一致。由于标定系数随时间变化，所以要针对特定问题的时间段进行实地标定。

英文摘要：

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.
