| Abstract: | The paper analyzed the relative calibration and absolute calibration of four component borehole strain observation. By the theorem “sum of vertical components must be equal”, we can only obtain the ratio of site scale value of 3 sensors and the sensor which is as a constant element, but we cannot get site scale value, so it cannot solve relative calibration. By the relationship between tides and component strain observation value, the coupling coefficient can be calculated, but calibration of the elastic parameters cannot solve the problem of the absolute calibration of strain. |
