Research on the Application of Ground Penetrating Radar in Advanced Geological Prediction of Deep Buried Tunnels

Abstract

With the development of the social economy and the emergence of a large number of tunneling projects, the importance of over-advance geological forecasting in the safe construction of tunnels has become increasingly obvious, and it has also attracted a lot of attention from the academic community. In this paper, the measured radar data are analyzed to verify the feasibility of ground-penetrating radar in the overtopping geological prediction of deep-buried tunnels and the validity of data characteristics. By analyzing the overtopping geological data of ground-penetrating radar and verifying the results by excavation, the following conclusions can be obtained: in the process of overtopping geological forecasting, ground-penetrating radar has the characteristics of simplicity, convenience, and high accuracy, and the method can make anomalies in advance for the abnormalities in front of the tunnel's palm face, and it can provide accurate and reliable geological information to ensure that the tunnel project can be constructed safely.
