This study is to determine the predictability of the ground cavitation by GPR (ground penetrating radar) equipment. Hume pipe, PE pipe, Steel Pipe and EPS (expanded polystyrene) are buried in the test bed. According to detection results, the EPS was not well detected. It received a lot of interference signal of other buried things. Otherwise the buried pipes were well detected.
