| 摘 要： | 本文简略介绍了利用探地雷达探测黄河大堤堤身隐患的试验效果,初步探测的结果表明,探地雷达可以探测土堤堤身内部的洞穴;对土裂缝发育地段,雷达图象清晰;配合少量钻孔资料,可以沿堤身追索历史上溃决口堵层的顶底界并了解堵层的不均匀性。

| Abstract: | In this paper,a GPR testing work for hidden danger estimation within the Yellow River Embankment is presented. The preliminary results indicate that the animal-made cavity located in the embankment may be detected with GPR, and the pattern of developed soil fissure can be shown quite clearly on the GPR map, and the layer's early filled part of the burst dam as well as its border and inhomogeneity may be traced on the GPR record in coordination with a small quantity of borehole data. |
