分量应变和体应变可靠性检验及特殊事件影响对比分析

对泰安台不同类型钻孔应变仪的产出资料进行研究，分析分量应变仪的自检可靠性及其与体应变资料的相关性，以及在抽水干扰情况下的相关性。RZB-3仪两组互相正交的分量应变之和S1+S3、S2+S4的自检相关性达到0.999 9,其与体应变的相关性达到0.998以上。但在抽水干扰情况下，S1+S3、S2+S4自检相关性及与体应变的相关性均较差。

Reliability Testing of Component Borehole Strain Meter and Volumetric Strain Meter and Comparative Analysis on Data Impacted by Special Events

This paper compares the observation data of different borehole strain meters of Taian fiducial seismic station. We analyze the self-testing reliability of component borehole strain. The correlation of component borehole strain meter and volume strain meter in the normal state and during drawing water conditions is also studied. The correlation coefficient between S1+S3 and S2+S4, two orthometric components of RZB-3, is 0.999 9. The correlation coefficient between S1+S3 and S2+S4 of RZB-3 and volume strain is above 0.998. However, there is poor correlation when the instruments are disturbed by pumping.
