HIDDEN DANGER ESTIMATION OF GPR WITHIN THE YELLOW RIVER EMBANKMENT

Qi Mingsong (China University of Geosciences, Wuhan 430074)  
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.
