Photogrammetry and Tomography Technique methods, its comparison with the conventional methods of geotechnical laboratory testing

This paper presents the investigation and testing of the foundation of the Cliff, whom has deteriorated due to the hydraulic and massive ice pressure and its freeze thaw cycles, a visual inspection and core samples were taken for the core reconnaissance of rock formation and elastic properties of the rock strata.Exploring these cavities by using the Crosshole Seismic Measurements and Tomography Technique methods [6] and comparing it with the conventional methods of geotechnical laboratory testing and its results, These Methods of the Crosshole Seismic and Tomography Techniques are used to determine the dynamic elastic properties of subsurface materials, to detect the fracture zones, and to delineate geological boundaries. Also to give other information which assists in the analysis of the Cliff stability or any foundation in order to have the correct and suitable methods and ways that helps in the reinforcement, renovation or reconstruction of any geotechnical foundation.
