| 摘 要： | 以钻孔体应变为例,利用潮汐因子对钻孔体应变观测资料进行校正。结果表明,由于各台所处的构造条件、地形条件、钻孔条件不同,各台的校正系数也不同。校正系数隨时间变化比较稳定,变异程度系数最大约为4.1%最小仅有0.1%,表明校正结果相当好。文中给出了部分钻孔体应变台站观测资料的校正系数。该方法有计算简便、结果可靠、实用性较强等优点。

| Abstract: | In this paper,the authors take the borehole bulk strain as an example to correct borehole bulk strain data by tidal factor.The result shows that the coefficient of every strain is different because of the difference of the station structural condition,topographic condition and borehole condition.The coefficient is relatively stable with time,variation factor is about 4.1% at most and 0.1% at least,indicating that the result of the correction is quite well.This paper presents the coefficients of some observational data of borehole bulk strain stations.The method has the advantages in easy calculating,dependable result,practically using and so on. |
