Harmonic Analysis on the Observational data of Digital Volume Strain in Shandong

采用维尼迪科夫调和分析法求解山东体应变固体潮观测时值序列对理论值的偏离,得到正常时段各台各参量的特征值;结合应变观测资料变化特征的分析,对仪器运行状况进行了客观评价。同时,讨论了潮汐因子、相位滞后等参数与岩性及井孔条件的关系。

Using Venidikov harmonic analysis method, the tidal parameters of digital volume strain of Shandong Province have been studied to find their deviations to the theoretical value and to get the characteristic values of each parameter in normal conditions. The running state of every station is evaluated combined with the analysis on the observed data of body strain. And the relation among the tidal parameters, such as tide factor and phase lag, as well as the lithology and the conditions of the boreholes is discussed in this paper.
