| Abstract: | The karst cave is a typical geological hazard encountered in the construction of highway and rail transit in karst area,and the survey of its growth scope is the primary task for the treatment of karst cave.This article introduced the theoretical basis and work methods of cross-hole resistivity CT,and carried out the verification analysis on the applicability of this method in combination with practical sur-vey examples.The verification results showed that the cross-hole resistivity CT has the validity,feasibility and accuracy for the detection of karst cave development range. |
