水平四分量钻孔应变仪观测的是地表附近一点的水平应变变化. 但是其直接记录并非应变变化,应根据互检条件先进行实地相对标定(计算元件校正系数),然后用理论固体潮进行实地绝对标定(计算探头校正系数),才能进行应变换算,给出可作为应变变化使用的数据. 因为钻孔应变仪观测的是应变变化,所以实地标定和应变换算都需要用增量. 对于精确的研究,这些校正系数都可能随时间变化,因而需要根据具体问题按特定时间段对校正系数进行计算. 该文比较系统地说明了四分量钻孔应变观测资料换算和使用的基本步骤和具体方法,并以姑咱台的观测资料为例,给出了具体分析结果.

4-component borehole strainmeter observes horizontal strain changes near the surface. However, direct readings of the instrument do not denote exactly the strain changes. In order to obtain the data that can be converted in accordance with strain theory, relative in-situ calibration should be done first, and then absolute in-situ calibration. Since strainmeter virtually measures changes in strain status, increments should be used in conversion. For precise studies, in-situ calibrations should be carried out corresponding to the concerning period of time. As an example, the data from Guza station are processed and the results given.
