Lithological Profiling of Rocky Slopes using GeoReader Software Based on the Results of Ground Penetrating Radar Method

The paper presents the Ground Penetrating Radar (GPR) technique for the survey of deforming rocky slopes of the railway subgrades. The developed software GeoReader allows the delineation of the boundaries in soils, which compose the slope, and definition of the possible slip surface. We have summarized the results of the use of the technique in certain sections of the Far Eastern Railway.The current level of development in the sphere of geo-survey does not allow for the complete abandonment of costly and labor-intensive conventional survey techniques, such as boring. Nevertheless, in the near future geophysical methods will be able to provide complete information on the object of investigation.
