Abstract: This paper introduces the methods which is used to detect and control construction quality of tunnel supporting structure during the two stages,primary support and secondary lining,to which the authority apply the undestructive detection technique,according to the relevant standard and code.Firstly, the article briefly analyzes the radar image features such as empty galleries,steel struts,and lining thickness by using the technique of Ground Penetrating Radar (GPR) for images and image recognition of all kinds of defect in lining construction,based on practical engineering examples.Secondly, this chapter is to provide a brief survey of lining strength detecting techniques.Finally,via practical engineering examples,we test the effectiveness and reliability of whether lining concrete strength can meet design requirement with ultrasonicrebound combined method and whether tunnel supporting structure construction quality is good or bad with the technique of ground penetrating radar (GPR).
