The excavation of the jointed rock slope is studied, and the geometry is shown in Fig 6. Where two sets of parallel joints are assigned to the rock that are intersecting each other. The rock slope is excavated in 10 stages – The water table is at the ground surface at the initial state & throughout the excavation, it is lowered … Se mer In this segment, the equation for a non-linear rock mass in 2D is reviewed. The domain Ω contains discontinuities with the boundary of Γ𝑑, under the external traction t applied on Γ𝑡 and internal body force b and prescribed … Se mer The discretization of the weak form equation (1) in space with the extended finite element method is discussed in this section. This method shows that nodes are enriched based on the type of discontinuity. The … Se mer Two numerical examples of jointed rock slopes are solved using the XFEM technique and the results are compared by the explicit joint method. Se mer This study illustrates the application of the XFEM method for general cases where joints are intersecting each other. It was shown that this method is completely mesh-independent and the joints can be placed anywhere in the … Se mer Nettet3. Modeling of rock slopes To study the effect of joints pattern on the strength reduction factor (SRF), slopes with dips of 30, 45, 60, and 75 degrees and with joints pattern of Parallel deterministic, Parallel statistical, Cross jointed, Baecher, Veneziano and Voronoi were modeled with the same orientation, spacing and density.
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. NettetThe stress strain behavior of intact rock and the phenomena of friction along a single plane as well as the relation to the underlying mechanisms are reviewed. The behavior of the modeling material is consistent with that of most brittle rock. Results of the tests with jointed models which are also supported theoretically, show that the transition from …
