摘要
简述了天然电场选频方法的原理、计算公式和仪器使用方法 ,介绍了实测曲线的圆滑和以曲线背景为标准的归一化数据处理。通过在实际工作中的应用例子 ,说明了该方法在高阻覆盖区寻找岩溶洞穴和矿区中浅部采空区 ,评价工程地质状态 ,探查隐伏断裂、富水滑坡边界等方面具有快速、轻便、有效的优点。
Theory, calculation formulas and instrument usage of natural electric field frequency-selection method are briefly discusses. Processing methods of the field survey curves and normalizing data handling based on the curves are also introduced. By actual examples in field survey, the paper shows that this method is quick, convenience and validity in surveying of karst caves and middle-shallow orebodies, and can used in appraising engineering geology, detecting subsurface faults and searching boundary of water-saturated landslides in high-resistance rock covered districts.
