Ground penetrating radar is the high-new technique method of physical geography in recent ten's remaining years,and it has such merits as high differentiate rate and orientation nicety and expeditiousness economy and agility convenience and section straight view and real time image visions.And it is applied in rock-soil engineering reconnaissance,engineering quality zero damage detection,Hydro-geological investigation,geographical and resources study,environment detection and so on.In this paper,talking concrete quality detection of Maojin tunnel lining in Tai-zhong-ying railway as example,and expounding the application of ground penet rating radar RISK2 which is created by IDS company in Italy to detect existing cavities and non-dense defects within concrete lining of tunnel.
