摘　　要：为有效消除地形对EH4探测结果的影响,理论分析了在低频情况下,地形影响表现出静位移畸变而阻抗相位保持不变的特征。数值模拟了山峰地形、山谷地形条件下低阻体视电阻率的变化特点,并采用比值法进行了地形校正,结果表明比值法能有效消除地形的影响。In order to eliminate the effect of terrain on the EH4 detection results, it analysis topography of the low frequencies by theory. It shows that static displacement remains the same and impedance phase is distortion. It use numerical simulation method to research on the apparent resistivity of the low resistivity body in mountain terrain and valley terrain conditions and use the ratio method to topographic correction. The results show that the ratio method can effectively eliminate the influence of terrain.
