【Abstract】 In order to chose the position of high standard projects such as highways, bridges and embankments, it is necessary to determine the exising krast and its relative parameters. On the basis of obtained reliable geological information, the authors use the resistivity sounding method to survey a section of Ning Heng highway, and explain its ρ s information using reflection cofficient ( K ) method. The results show that the resistivity sounding method can exactly reflect the karst and determine its scale and space position, and so it has great prospects in this field. [更多还原
