摘　　要：直流激发极化法是现代地质勘查中应用较为广泛的地球物理探测方法之一,该方法能快速获取地质体的极化率和电阻率等电性参数。但受地形起伏的影响,通过该方法所获取的电阻率参数往往不是地质体的真实反映。运用ANSYS有限元分析软件能快速准确的对复杂地形条件下不同装置类型的电阻率开展二维、三维地形改正,使改正后的电阻率参数能反映地质体的真实情况。通过在研究区运用ANSYS软件对野外采集的电阻率数据进行地形改正,取得了良好效果,可以为广大地球物理工作者提供技术参考。DC polarization method is one of the most widely used geophysical exploration methods in modern geological exploration.It can quickly obtain the electrical parameters such as polarization and resistivity of geological bodies.However,due to the influence of topographic relief,the resistivity parameters obtained by this method are often not the true reflection of geological body.ANSYS finite element analysis software can quickly and accurately carry out two-dimensional and three-dimensional terrain correction for resistivity of different device types under the complex terrain condition,so that,the resistivity parameters after correction can reflect the real situation of geological body.By using ANSYS software in the study area,terrain correction of resistivity data collected in the field has achieved the good result,which can provide a technical reference for the majority of geophysicists.
