Abstract Combining with practical situation of ground penetrating radar (GPR) application in tunnel lining detection practice，the principle of electromagnetic wave of nondestructive detection technology is presented，and then the detection methods are introduced. Detection results and characteristics of wave figure which covers lining thickness，lining defect，and bar distributing situation are shown. Feedback suggestions of construction as well as problems encountered in practice when adopting GPR to detect tunnel lining quality are given. Finally，related conclusions and suggestions are proposed.
