摘要
电测深是寻找隐伏花岗岩体的一种主要方法.但因易受浅部电性体和旁侧电性体的干扰,往往效果较差.本文提出了一种压抑这类干扰的滤波方法,使用L参数绘制的断面图,能突出地显示出隐伏岩体的异常.
In detecting a deep-seated rock mass with geosounding, lateral inhomogeneities at or close to the surface will give a great effect upon resistivity measurements. A method is developed by the author to suppress such disturbances by a high-pass filtering of the data in order to give a prominence to the anomaly of a concealed granite mass. Some satisfactory practical examples are cited.
