摘要 通过不同岩石和岩样不同力学状态下的交流阻抗谱测试发现,岩石的交流阻抗谱结构完全相同,不同的岩石交流阻抗谱有一定差别,同一岩样相同物理状态下交流阻抗谱相对稳定,由此得出岩石的交流阻抗谱是岩石材料对交流电信号的反映。岩石的种类和岩样的物理状态与交流阻抗谱之间具有因果关系和线性函数关系,可以通过交流阻抗谱特征来研究岩石的物理性质。 AC impedance of rock is tested by CHI600A electrochemical work station. The result shows that the forms of rock AC impedance spectra are the same: and the AC impedance spectra of different rocks and identical phisico-mechanical environment have some difference: and the result of same rock AC impedance test is stabilized in the same physico-mechanical environment. Based on the test, the conclusion is that the causality and linear functional relation are existed between rock and AC impedance spectra. AC impedance can disclose the properties of rocks.
