K剖面法在丹江口库区高切坡治理勘探中的应用

Application of K-section method in treatment survey of high cutting slope in Danjiangkou Reservoir Area

K剖面法是对称四极法中能够用较小的供电极距达到探测目的层深度的处理方法。为解决传统K剖面法人工校正地形效率低、精度低的问题,使用"K剖面法综合处理系统"软件来处理电阻率数据,既利用了高密度电法数据量大的优点,又弥补了高密度电法反演处理中勘探深度与供电极距比偏小的问题。该方法经过在南水北调丹江口库区高切坡治理勘探中使用验证,取得了良好效果。

K- section method is a symmetrical quadrupole method, which can reach the target depth with less＇ electrode dis- tance, while high density resistivity method can collect large amount of resistivity data at each time. In order to solve the problem of low efficiency and accuracy of terrain calibration, the software of K - section integrated processing system is used to process re- sistivity data, which can not only take the advantage of large amount of resistivity data, but also can solve the problem of low ratio of target depth to electrode separation. Its application in survey of high cutting slopes in the Danjiangkou Reservoir area of the South - North Water Diversion achieves a good effect.
