Abstract
ABSTRACT
The ground‐penetrating radar (GPR) method is increasingly applied to the quality evaluation of large‐scale civil engineering projects due to its accuracy, non‐destructive application and rapidity. In this paper, we discuss the acquisition and analysis of GPR data acquired in the Kunlun Mountain railway tunnel, China. We evaluate the tunnel lining quality and detect the hidden flaws in the lining, which are used to direct the subsequent grouting. Finally, GPR is used to assess the quality of the grouting. The results verify the flexibility and effectiveness of this method.
