Stability Analysis of Jointed Rock Slope by Strength …
NettetIn the process of stability analysis of open pit slopes in jointed rock mass, a number of steps and levels of analyses are required, from local bench design to overall stability of the high wall open pit rock slopes. under bed tornado shelter
Base Friction Modeling of Toppling Failures In Jointed Rock Slopes
NettetFigure 10 shows a jointed rock slope failure occurred in Mianzhu, Sichuan, China. Slope inclination is about 45°; there are two sets of joints in this slope, set 1 parallel to the slope 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 Nettet31. mar. 2024 · This technique stimulates the spread of stress waves in the jointed rock mass owing to dynamic loading caused by the blast.
