| 摘 要： | 泉州地区目前存在的三套TJ-2C钻孔体应变仪整点值都能清晰地记录到应变固体潮汐,分钟值能记录到部分远大震应变波、震前异常阶跃等动态信息。由于不同的测点因其所处地质构造和钻孔自身岩性、岩石完整性、埋深等情况不同,其受干扰的影响程度和监测地震前兆异常的能力都可能存在着不同,并且观测曲线表现为较复杂的异常形态。对2015年这三套仪器观测资料进行对分析,从中找出更能真实反映地球内部应力变化的测点。

| Abstract: | Integral point value of three sets of TJ-2C borehole body strain in Quanzhou can clearly recorded the earth strain tide.The Minute value can be recorded to some strain wave of huge remote earthquakes,the abnormal step before the earthquake and other dynamic information.Due to the different measuring points,the geological structure,the drilling itself,rock integrity,depth and so on,the precursory anomalies disturbed and the earthquake monitoring ability may be different.And the observation curve is more complex.In this paper,we analyze observational data of the three sets of instruments ranking 2015 and find out the measuring point which more truly reflect the changes in the earth’s internal stress. |
