Analysis of instability mechanisms of a high rock prism standing on a cliff face
The analysis of possible failure mechanisms of a 50-m-high rock prism is presented. The case well represents a situation typical of many rock cliffs. The reconstruction of the geometry through remote and direct surveys and the mechanical characterization through laboratory and in-situ tests allowed to build a geotechnical 3D model. Analyses were conducted with the finite difference code FLAC3D where discontinuities are reproduced by interface elements.
