On the basis of the Ground Penetrating Radar detection of badger caves in embankment at Huaishu River
the structural characteristic of badger cave is analyzed; and the representative radar image characteristic is put forward. Then
the locations
depths and direction of badger cave channels are deduced for the cave remedy reference. The detecting results indicate that the GPR has the advantages of device portability
low site requirement and easy of adding detecting lines at various directions; and it is a very effective detecting device for shallow cave channels.
