裂隙非均匀分布岩石中的电位及视电阻率计算

计算了在均匀高阻介质中含有低阻裂隙的岩石的电场分布，并由此推导出裂隙非均匀分布的岩石中视电阻率的计算公式．结果表明，裂隙的埋深、规模、走向（平行或垂直视电阻率测线）以及真电阻率等，对视电阻率的观测和计算结果都有不同程度的影响．本文结果对视电阻率法用于地震分析预报提供了一种有效的计算方法． 

ELECTRIC POTENTIAL DISTRIBUTION IN ROCK CONTAIN-ING NON-UNIFORM CRACK AND APPARENT RESISTIVITY CALCULATION

In this paper, we compute electric field distribution in high resistance rock containing low resistance crack, deduce calculation formula about apparent resistivity in rocks containing cracks which are non uniform distributed. The result shows that the crack depth from the earth surface, crack scale, crack strike(parallel or vertical to the measuring line of apparent resistivity), crack really resistivity etc , have influence on observation and computing result of apparent resistivity. The result of this paper provide an effective compute method for earthquake analysis and prediction by using apparent resistivity method.
