在地形起伏情况下进行电阻率法工作时,必须压抑地形干扰影响,突出地质体异常,达到较好的地质找矿效果.消除地形干扰的途径在于光要获得纯地形的视电阻率曲线,然后再对迭加有地形影响的实测异常进行改正.二度角域点源电位的解释解已经导出,可通过电子计算机计算出任意二度复杂地形近似的点源视电阻率畸变曲线.实际上很多地形都可近似看成二度体地形,譬如一般的三度体山谷;山脊的山顶走向长度大于1.5AO,测线在山顶任一部位正交通过;任意三度体山脊,测线在半坡山腰通过;以及山
Resistivity method in the case of terrain fluctuations in the work, we must suppress the impact of terrain interference, highlighting the anomalies of geology, to achieve better geological prospecting results to eliminate terrain interference lies in the light to obtain pure terrain apparent resistivity curve, and then Then the measured anomalies superimposed with topographic effects are corrected.The second-order angular domain point source potential solution has been derived, by computer calculation of any second-order complex terrain approximate point source apparent resistivity distortion curve.In fact, a lot of Terrain can be approximated as a second-degree body topography, such as the general third-degree body valley; mountain ridge to the length of more than 1.5AO, measured at any point on the top of the mountain perpendicular to pass; any third body ridge, the survey line in Banpo Mountain pass; and mountain
