摘要
对承载岩石地电阻率各向异性变化的实验研究结果与大震孕育过程中现场观测到的地电阻率各向异性变化特征进行了对比分析讨论。结果表明，孕震过程中地震现场地电阻率各向异性变化特征与承载岩石地电阻率各向异性变化的实验结果相近或相符，也与岩石破裂过程中裂隙发展的力学实验结果相一致。
This paper conducts a comparative analysis and discussion on the experimental resultregarding the georesistivity anisotropic changes in the pressed rocks, and on variationalcharacteristics of georesistivity anisotropy in strong earthquake preparation. The resultsshow that the variational characteristics of georesistivity anisotropy during seismogenicprocess are as same as those of the pressed rocks, and they are also as same as the fracturedevelopment during rock rupture in mechanical experiment.
