| Abstract: | The authors briefly introduced the operating principle of GPR and its method and technique for investigating the subterranean cavitation, with some subterranean cavitation inspection of groundwork exploration in Guangzhou as an example, analyzed the radar wave group characteristics of subterranean cavitation, and summarized the anomaly characteristics of the time-depth sections of the GPR. The method has the characteristics such as high speed and precision as well as available sequential results. The excavation verifies that the anomaly characteristics of the GPR accord with true position of the subterranean cavitation. |
