Abstract:

Through anylyzing the Karst survey result of the right bank in the reservoir area of Wanjiazhai hydro- junction, the application of GPR technology in the survey of Karst is studied. The GPR technique and its working method principle are introduced. The abnormaly of radar wave field distribution produced by Karst is analyzed, and the Karst cavern and fracture range are detected by GPR technique. Verified results show that the GPR technique is effective to detect karst at shallow depth.
