| 摘 要： | IntroductionIn multidisciplinary research of earthquake predication, the geoelectric method is one of the important branches. It takes the electric phenomenon or the electric property changing of the earth medium in seismogenic process as the studying objects, and it is the important composing portion of the earthquake-development comprehensive research. The electric parameters of the earth medium, mostly the resistivity, are the main body in geoelectric research.Experiments indicate (LU, et …

| Abstract: | In this paper, the formula of electric field distribution and ground apparent resistivity of high resistance rock medium containing low resistance crack are deduced and simulated. The result shows that interstitial parameters, such as buried depth, scale, strike, and real resistivity, etc, have influence on observation and computing result of apparent resistivity. This study provided a useful foundation for earthquake prediction using apparent resistivity method. |
