VIVIANA BONILLA-SIERRA
(doctorante,L3S-R - Grenoble), viendra nous parler de ses travaux de thèse portant sur :
The use of photogrammetry and 3D Discrete Element Models to better assess Rock Slope Stability
Structural and mechanical analyses of rock masses are key components for rock slope stability assessment.
The complementary use of structural analyses and discontinuum numerical modeling provides a methodology that can be applied to analyse complex 3D rock mass configurations.
However, fracture persis-tence is generally assumed and can lead to inaccurate modeling and misleading conclusions.
To overcome this limitation, a recently developed DFN-DEM (for Discrete Fracture Network - Discrete Element Method) model which describes both yielding along pre-existing discontinuities and fracturing of the intact rock matrix is used in combination with a photogrammetry technique to assess the stability of potentially unstable rock slopes.
