Abstract Geological radar, which is nondestructive, fast, convenient and economical, are widely used in the field of archaeology and cultural relics protection. In order to find out the rock fractures surrounding Fenxian temple, the distribution of fracture zones in rock mass and the Quaternary overburden thickness at the top of Fengxian temple so as to provide the basis data for ooze water prevention and control of Fengxian temple, the authors employed the geological radar non-destructive testing technology to the protection engineering of Fengxian temple. This paper expounds the basic principle of geological radar and detection methods and focuses on the application of geological radar to the Fengxian temple's protection engineering. The detection results show that the rock mass at the top of the Fengxian temple is complete, and the crack and fracture zones between the Giant Buddha and the Fairy Cave are numerous, forming the crossed network seepage channel. At the top of Fengxian temple, the Quaternary overburden is concave, which is conducive to the rain water storage and retention, with the thickness between 1.0~2.2 m. The engineering practice indicates that using geological radar to survey the distribution of fracture zones of rock mass and the Quaternary overburden thickness is feasible, and that the geological radar has considerable application prospect in rock and soil conservation.
