Stability Analysis of Jointed Rock Cutting Slope Based …

NettetExfoliation joints following the topography of inclined valley walls, bedrock hill slopes, and cliffs can create rock blocks that are particularly prone to sliding. Especially when the toe of the slope is undercut (naturally or by human activity), sliding along exfoliation joint planes is likely if the joint dip exceeds the joint's frictional angle. NettetTwo numerical examples of jointed rock slopes are solved using the XFEM technique and the results are compared by the explicit joint method. Slope with Voronoi joint network In this example, a jointed rock slope is examined to ensure stability. The geometry of the slope is shown in Fig 4. hd wallet setup golden west casino employment

NettetTherefore, in this paper, based on the upper-bound limit analysis method and modified M–C failure criterion, an improved failure mode of multislider of rock slopes is established by assuming that the first m − 1 sliders are shear failures and the other n − m + 1 sliders are tensile failures. NettetWe examine the stability of the excavation of part of a jointed rock mass, leaving a sloped embankment. This problem is chosen mainly as a verification case because it has been studied previously by Barton (1971) and Hoek (1970), who used limit equilibrium methods, and by Zienkiewicz and Pande (1977), who used a finite element model.
