【Abstract】 This paper gives the brief introduction to precision location and high resolution of georadar in its applieation for investigating of underground targets and infering the collapsing cause on the river dyke of material deposit farm of Chongching lron and Steel Group. Another example of application of the georadar test is the Yellow River embankment where the soil fissures. of the burst clam at the hastily filled part and the culvert have been found out. The examples stated above reveal that in detecting hidden danger of river dykes, georadar investigation possesses wide prospects.更多还原
