利用三层厚壁筒组合模型，给出不同类型体应变的相互转换关系，分析模型参数变化对3类体应变仪观测的影响。通过对全国60多个台站的体应变观测资料分析，发现钻孔的气压系数与潮汐因子无简单对应关系。利用固体潮标定不同台站的体应变到统一系统的体应变，结果表明，多数台站存在体应变潮汐因子观测值比理论值明显偏小现象，推测可能与钻孔存在非完全耦合有关。

In this paper,based on the combined model of three thick wall cylinders,the mutual con-version formula between different types of borehole strain is given.The effect of model pa-rameters on three types of borehole strain observation is analyzed.Through analysis of the strain data on more than 60 stations,it is found that there is no simple correspondence be-tween barometric coefficient and tidal factor on the same station.By earth tide,the strain of different boreholes is calibrated into the unified system strain.The results indicated that many strain tidal factor observation were significantly smaller than the theoretical value. Therefore,that may be related to borehole incompletely coupling.
