Abstract Exemplified by the typical radar profile measured in the karst area of Guangxi, this paper deals with the practical result obtained by the application of the ground-penetrating radar to the detection of the properties and spatial shapes of the tunnel karst and points out the construction environment and lateral influence problems that deserve attention in practical application.
