| Abstract: | The development of ground-penetrating radar and its basic principle of GPR wave propagating underground is introduced. In virtue of actual project, the hidden karst under the fifth pier of W7 part in Yi-wan railway is detected successfully by assigning survey lines reasonably, considering the characteristics of GPR picture and analyzing the GPR picture seriously. It is proved by practice that the method of GPR is a rapid, efficient, economic and reliable method to detect the hidden karst. |
