| Abstract: | This paper briefly introduces the working principle of ground penetrating radar, and a hollow slab bridge in dam crest highway traffic bridge of a power station is detected by using ground penetrating radar. Through analysing the geological radar data, it shows that the value of wave velocity is very important in measuring concrete thickness by GPR. The radar image can determine the thickness of slab and beam concrete and the position of steel bar well. The ground penetrating radar has good effect in detecting the quality of hollow slab and beam. |
