Abstract: Combined with the application of ground penetrating radar in the advance geological forecast of Luoqu tunnel,the technical mechanism of the radar,the layout of the lines and the data collection are introduced in general.Based on the data processing and analysis,combining with the results charts of ground penetrating radar,the regional geological condition in the inspection area is described.Through the project example,the role of the advance geological forecast with the geological radar technology is expounded,and a forecast specific guidance for the tunnel construction is provided.The real-time geological forecast data are provided for the construction process to ensure the safety of the construction,and the basis for the necessary design changes is also provided.In view of the engineering application,the choice of the advance geological forecast method and the economic comparison are summarized,which could provide the reference for other similar projects.
