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

K-section method is a symmetrical quadrupole method,which can reach the target depth with less electrode distance,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 resistivity 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.
