| 摘 要： | 基于泰安台2013年洞体应变观测资料,首先利用维涅第科夫(Venedikov)调和分析方法计算洞体应变测项的潮汐因子和相位滞后,并以潮汐因子的稳定性对观测资料进行了质量评价。同时对观测仪器的2个测项进行解算,并提取相关应变参数进行对比。在此基础上,选取泰安台资料质量较稳定的体应变数据进行了应变参数时间序列计算,并对2套仪器观测数据进行了对比。通过分析,认定应力场存在异常,并对比分析了应力场异常与重力场异常的对应关系。

| Abstract: | Based on the cave strain observation data in 2013 at the Tai''an station,we use Venedikov harmonic analysis method to calculate cave strain measurement and phase lag of the tide factor,and evaluate qualitatively the stability of the tidal factor for the observational data evaluation. At the same time,the 2 measurement items of the observation instrument are calculated,and the correlation strain parameters are extracted and compared. On the basis of this,the strain parameter time series calculation is carried out on the data quality of Tai''an station,which is relatively stable,and the 2 sets of instruments are compared. Through the analysis,it is found that the stress field is abnormal,and the corresponding relationship between the anomaly of the stress field and the gravity field is compared and analyzed. |
