Analysis of Electrical Resistivity Method

Application of Extended Kalman Filter Method to Jointed Rock Mass Survey

Abstract

The electorical resistivity prospecting is a useful method to detect the distribution of discontinuities in rock mass.
Authors firstly verify the algorithm of inversion analysis method, which developed for 3D-FEM. to identify resistivity values through an extended Kalman filter by case studies of 3-D FEM numerical simulation. Secondly based on the results of this simulation, an application of new method to the jointed rock mass survey is done.
It is concluded that the inversion technique, which we have established through an extended Kalman filter, works effectively.
