The application of Ground Penetrating Radar in advanced prediction of tunnel

Advanced prediction of the geological condition of anterior rock near tunnel's work area in the hydraulic tunnel construction not only to protect the safety for the construction unit, but also can save a lot of manpower, financial and material resources. Ground Penetrating Radar, GPR for short, has been widely used for its easy operation, rapid, non-destructive, veracity, intuition and etc. In this paper, the introduction of basic working principle and the application and skills of GPR in advanced prediction of water delivery tunnel was produced.
