地质雷达在大坝交通桥空心板桥梁检测中的应用

Application of Ground Penetrating Radar in Detection of Hollow Slab Bridge in Dam Traffic Bridge

该文简要介绍了地质雷达的工作原理,并利用地质雷达对某电站坝顶公路交通桥空心桥板梁进行了检测。通过雷达检测数据分析,表明波速取值在地质雷达测混凝土厚度中的重要性,雷达图像可以很好地判定板梁混凝土厚度、钢筋位置:地质雷达在空心板梁质量检测中取得了较好的应用。

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.
