利用多层厚壁筒组合的力学模型，分析介质力学性质变化对钻孔面应变耦合系数的影响。利用引潮力标定方法对观测资料的研究表明，“地层、水泥环和钢筒”模型不能完全反映观测条件，考虑原地应力卸载影响的四层介质耦合模型，与观测环境基本相符，可以对观测结果进行较合理解释，同时发现钻孔面应变耦合系数的大小与台站的背景应力场存在一定关系。

In this paper , using more thick-walled cylinder force models , we analyze the impact of media mechanics properties change on coupling coefficient of borehole plane strain .Studying on the observation data with tide generating force calibration method show that ,“the stratum , cement and steel tube” model cannot fully reflect the observation conditions , considering the four layers coupled model influenced by in situ stress unloading is basically consistent with the observation environment , and the measured result can be more reasonable explained .In addition, we also find that there is a certain relationship between the borehole plane strain coupling coefficient size and background stress field of the station .
