Application case of GPR in tunnel geological prediction

This thesis briefly introduces the importance, content, and common methods of tunnel geological prediction, taking Sichuan Yaan Daxiangling tunnel engineering as an example, expounds the basic principle and prediction methods of GPR prediction. According to detected data analysis, it successfully predicts rich watershed in front of the tunnel face. Thus, it ensures the tunnel safe construction.
