摘要
这里以对称四极装置为例,采用有限元法实现各种地形地电条件的时间域二维电阻率正演数值模拟,运用比值法原理提取地形响应参数,通过对比分析不同电性条件和不同地形条件下的地形响应曲线,得到地形响应参数随地形与介质电阻率变化的一系列规律,并进一步完善了比值法地形校正方法。
Taking the symmetric quadrupole device as example,the geoelectric forward numerical simulation is presented by using the finite element method to achieve the two-dimensional time-domain resistivity of various terrain conditions and using the principle of ratio method to extract terrain response parameters.through comparative analysis of different conditions and different electrical terrain response curve terrain conditions,terrain response parameters obtained with the terrain and a series of medium resistivity change the law,and further improve the ratio method topographic correction methods.
