探地雷达和高密度电阻率法在围垦堤坝探测中的应用

THE APPLICATION OF GROUND PENETRATING RADAR AND HIGH DENSITY RESISTIVITY METHOD TO THE DETECTION OF INNING DAM

基于抛石层与淤泥质黏土层存在较大电性差异,采用探地雷达和高密度电阻率综合法对某围垦堤坝抛石层进行探测,获得了抛石层的范围和厚度。经钻探验证,探测结果与实际较吻合,表明利用探地雷达和高密度电阻率法可有效探测围垦堤坝抛石分布及厚度。

In view of the electrical difference between the riprap layer and the argillaceous clay layer, the authors used synthetic methods of ground penetrating radar and high-density resistivity to detect the riprap layer in an inning dam. The result shows that the limits and thickness of the riprap detected by the synthetic methods are quite coincident with those detected by the drilling. This indicates that synthetic use of ground penetrating radar and high density resistivity method is very effective in riprap layer detection.
