高台地震台钻孔应变观测资料的分析

Analysis and evaluation of borehole strain observations at Gaotai Seismic Station

对高台地震台2008—2012年的YRY-4分量钻孔应变观测资料进行处理与分析,结果显示:高台台YRY-4分量钻孔应变仪运行良好,产出的观测数据连续、稳定、可靠;各个分量应变潮汐因子及相位变化相对稳定,相对误差较小,符合地壳形变观测技术规范要求;各个分量应变观测数据具有明显的周期特性和同向漂移变化。

We process and analyze the YRY-4 component borehole strain observations at Gaotai Seismic Station from 2008 to 2012. Results show that： YRY-4 component borehole strain-meters work well at Gaotai Seismic Station, and the observations are continuous, stable and reliable;The strain tidal factor and phase of each component is stable with small errors, which meet the Technical Standard of the Crustal Deformation Observation;The observed strain of each component presents obvious periodic, and different component slants to the same direction.
