库尔勒地震台四分量钻孔应变观测资料可靠性论证

对库尔勒地震台的巴伦台、库米什、小泉沟子台3套四分量钻孔应变仪观测数据进行多角度可靠性分析，除按常规由4个元件的读数计算2个面应变数值及相关系数值（数据自检）外，做以下补充：对潮汐因子内精度进行计算；通过相对标定元件格值，视矫正幅度大小及对数据自检效果进行改进；与同一时段相邻区域陆态网络形变观测资料进行对比，进一步论证观测资料的可靠性。结果表明，3个子台的应变观测数据可靠，能够真实反映所处区域的构造活动和应变，可以用于区域地震预测和地震科学研究。

Reliability demonstration of four component borehole strain observation data at Korla Seismic Station

The multi angle reliability analysis of observation data of three sub-stations of four component borehole strain gauges at Korla Seismic Station is carried out. In addition to the routine numerical calculation of 2 plane strain and the correlation coefficient (i.e. data, self-test) with the 4 component readings the internal precision of tidal factors is also calculated as supplementation. Through relative calibration of element lattice value, virtual amplitude correction and improvement on the effect of data self-check, the observation data are compared with deformation observation data of adjacent land state network in the same time segment and the reliability of observational data is further demonstrated. The results show that the strain observation data of the 3 sub-stations are reliable, which can truly reflect the tectonic activity and strain in the area, and can be applied to regional earthquake prediction and seismological research.
