一、引言我国开展分量式钻孔地应力(应变)观测已经有30多年的历史,获得了大量宝贵的观测数据。目前,第二代分量式应变观测系统(例如RZB-1型电容式应变仪),已经将观测精度提高到10~(-10)。但是,如何处理和解释这些资料,从中提取出可靠的地应力信息,尽管已经有不少作者进行过论述,但仍然是一个没有得到完善解决的问题。例如至今还没有文献阐述观测资料与理论固体潮是否符合,因而不能说明观测结果的可靠性。这个
I. INTRODUCTION China has carried out component borehole stress (strain) observation over 30 years and obtained a large amount of valuable observation data. At present, the second-generation component strain observing system (such as the RZB-1 capacitive strain gauge) has improved the observation accuracy to 10 -10. However, how to deal with and explain these data and extract reliable information about geostress, though many authors have already discussed, are still a problem that has not been solved well. For example, there is no literature to show whether the observed data is consistent with the theoretical solid tide so that it can not explain the reliability of the observed results. This one
