The layer characteristics and the difference of electromagnetic properties of the section of the blasting compaction for filling stone have the basic physical testing precondition of ground penetrating radar (GPR). The testing practice of a beach dike in Dongtou of Zhejiang Province
shows that the bottom depth
width
the waist width etc.of the deep thick ripped rock layer
whose bottom depth reaches 35m
can be tested using GPR when the 16MHz lower frequency antenna and the appropriate testing parameters are used. But it is difficult to recognize the mixing layer of soil and stone in the bottom.
