System reliability approach to rock slope stability
A systematic quantitative methodology for the reliability analysis of stability of rock slopes is presented. A sliding mass resting on an inclined plane and composed of two blocks separated by a vertical tension crack is considered, and a disjoint cut-set system formulation is proposed, with each cut-set corresponding to a different failure mode of the slope. Methods for the evaluation of the s...
متن کاملRock Slope Stability Analysis Using Discrete Element Method
Rock slope stability depends very much on the strength features of the rock and the geometrical and strength characteristics of the discontinuities (e.g., roughness, wall strength and persistence). Since a rock mass is not a continuum, its behavior is dominated by such discontinuities as faults, joints and bedding planes. Also, Rock slope instability is a major hazard for human activities and o...
متن کاملThe Effect of Discontinuity Persistence on Rock Slope Stability
l f Discominuity persistence has a major effect on rock mass resistance (strength) but, as direct mapping ofdiscominuities imemal to a rock mass is not possible, persistence is a difficult parameter to measure. As a result, the conservative approach of assuming full persistence is often taken. /n this paper a method is developed for relating rock mass stability and hence persistence to the geom...
متن کاملRock slope discontinuity extraction and stability analysis from 3D point clouds: application to an urban rock slope
This paper presents an application of a recently developed methodology for the identification and analysis of flat surfaces affecting rock masses using 3D LiDAR point clouds(Riquelme et al., 2013 submited). The used methodology has been applied to calculate the algebraic equations of the different discontinuities of a rock slope through a methodology based on next three steps: (a) local curvatu...
متن کاملLarge-scale rock slope failures in the eastern Pyrenees: identifying a sparse but significant population in paraglacial and parafluvial contexts
This first overview of large-scale rock slope failure (RSF) in the Pyrenees addresses the eastern third of the range. Around 30 principal RSFs >0.25 km and 20 lesser or uncertain cases have been identified from remote imagery and groundtruthing. Compared with other European mountain ranges, RSF incidence is relatively sparse, displays no obvious regional trend or spatial clustering, and occurs ...
