地震电阻率实验研究新进展及展望

New progress and prospect of earthquake-related resistivity experiments

  • 摘要: 准确的地震预报是减轻地震灾害的有效手段之一. 地电阻率是一种被证实了的、有效的地震前兆参量,在我国自1966年以来的地震监测预报工作中发挥了且正在发挥着重要的作用. 伴随着地电阻率在地震监测预报中的应用,关于电阻率变化特征和规律及其机理的实/试验从上世纪60年代以来从未间断. 在实/试验中,主要采用了单极距观测系统. 它的测量值代表了其探测深度到地表的整个深度层的综合效应,无法确定地下各层的贡献. 为此,一些研究者探索新的地电阻率观测系统,进行了地电阻率多极距和电阻率层析成像观测的实/试验研究. 本文对单极距观测系统的实/试验结果进行了简述,详细介绍、总结了多极距和电阻率层析成像观测的实/试验研究状况,最后提出了进一步研究的可能方向.

     

    Abstract: Precise prediction is an effective way to prevent earthquake and reduce disaster. Geoelectrical resistivity is a proofed and effective earthquake precursor and has played and been playing important role in earthquake monitoring and prediction in our homeland since 1966. Lab/field experiments on characteristics, trend and mechanism of resistivity changes have not been ceased since 1960s associated with the applications of geoelectrical resistivity in earthquake monitoring and prediction. Single-separation array observation system has been primarily employed in these experiments. The measured resistivity by this system stands for the general contribution from its detection depth to the surface. As a result, the contribution from each layer cannot be determined by this system. Consequently, some workers have explored new observation systems and conducted experiments in lab/field on multi-separation array observation and electrical resistivity tomography. In the present paper, experimental results from single-separation array observation system are briefly described, while those from multi-separation array observation and electrical resistivity tomography are introduced and generalized in detail, and at last possible new research interests are suggested.
