Abstract: |
Statements about stability, weathering behaviour and possible rockfalls affecting a real rock massif were made possible by creating a 3D surface/volume model, using as example the "Großer Wehturm" rock massif, using the high-resolution laser scanning process together with rock mechanical 3D model calculations. The emphasis of this paper is the mathematical modelling, particularly the generation of the 3D model from the surface point cloud and the simulation possibilities. The numerical calculations are based on the Discrete Element Method, considering the rock matrix and joint or bedding interfaces. The 3D modelling delivers, in addition to answers to questions about the extent and degree of deformations and movement mechanisms, knowledge relevant to the transfer of the procedure to other locations. |
