Effects of Discontinuities on Rock Slope
Abstract Discontinuities possess a major role in the stability of a rock slope and also influence the behavior and failure patterns of it under different loading environments. In this paper, the effects of different joint patterns on the stability of a 260-m-high slope with a face angle (ψf) of 55° are examined under different loading environments. Under gravity loading, when the slope is having out-of-plane joints, it becomes more stable when the dip of the discontinuity (ψ) increases, although failure pattern changes. Plane and rotational failure patterns are observed when ψ becomes less than and greater than ψf, respectively. In case of joints dipping into the plane, the shear displacement becomes significantly less than the previous cases, which indicates a toppling failure. Similar observations can be made under rainfall condition and under seismic loading. In the seismic case, shear displacement and block rotations are obtained. The failure mechanisms of the slopes under different joint sets are investigated by obtaining displacements at different time intervals of the seismic loading. Universal distinct element code (UDEC 4.0) is used for all the simulations.
