| description | Evidence of a complex failure mechanism which involved both a distinct planar sliding surface, in addition to block-flexural toppling has contributed to the instability at a Penrhyn slate quarry. The objective of this study is to identify parameters that control instability in the rock slope, which has been based on the parametric analysis of Discrete Element Method (DEM). The methodologies combine the discrete element method of analysis together with field observation. From the study, it was found that, factors that controlling rock slope instability are dip of discontinuity, water,weathering grade and slope angle. The results supported the evidence from the Penrhyn failed slope, where the modelling has confirmed the influence of structurally dipping at 78°of cleavage in slate and the water that fills in the crack and developed the water pressure that triggered the failure. |
