Abstract
|
High density resistivity method from the principle point of view , belongs to the resistivity method . High density multi - electrode cloth electrode and realized running pole and automated data acquisition , has many advantages. Engineering investigations , hydrogeology , environmental engineering and more widely, especially in karst , hydrology , construction, testing and other areas . However , the correct inference and interpretation of the undulating terrain of high-density electrical prospecting had a greater impact . Firstly, brief exploration of the terrain of the high density resistivity method to influence the research status and progress of the correction . Again using the two-dimensional finite element method , the preparation process of two-dimensional numerical simulation of the high and low resistance anomaly geological model of the valleys, ridges upright and level terrain . Calculated in accordance with the high density electrical prospecting wenner quadrupole device different points of the depth of the apparent resistivity . Finally, analysis of the impact of the terrain of the DC resistivity prospecting , Schwartz-Christoffel mapping conformal transformation forward modeling data above and terrain correction studies . Concludes the paper , through the processing of the theoretical models and field engineering , conformal transformation has a good effect of high-density electrical prospecting rolling topography and geological conditions of the terrain correction .
