铁岭地震台洞体应变参数解算与分析

CALCULATION OF THE STRAIN PARAMETERS BY CAVE STRAIN OBSERVATION RESEARCH OF THE TIELING STATION

针对铁岭地震台洞体应变观测资料,利用Venedikov调和分析方法计算铁岭地震台站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;以铁岭地震台洞体应变讨论两分量观测解算平面应变参数,结果表明:铁岭洞体应变的最大剪应变τ和面应变s在2006年和2009年出现了明显同步转折,可能反映了铁岭地震台及附近地区的应变出现了调整。

In Tieling Seismic Station body piercing strain observation data, the use of Venedikov harmonic analysis method to calculate body piercing strain measurement of Tieling Seismic Station, tide factor and phase lag, and the stability of the tidal factor on the observation data quality evaluation; Discuss two component in Tieling Seismic Station body piercing strain observation calculating plane strain parameters, the results show that the maximum shear strain tau tieling body piercing strain and strain s in 2006 and 2009, there is an obvious synchronous twist, may reflect the strain and adjustment appeared in the region near the Tieling Seismic Station.
