Calculation of Factor of Safety for a Rock Slope Reinforced with Passive Bolt under Plane Failure

Rock slopes are always subjected to failure due to external or internal forces. Based on the characteristics of in-situ rocks, there are numerous type of slope failures. Plane failure is one of them, in which a certain portion of the rock mass slide or fail along a particular plane. To avoid the failure and reinforce the slope, rock bolting is used. Provision of bolts increases the shear strength at failure plane that enhances the factor of safety. The present paper summarized a methodology for calculation of factor of safety for rock slope reinforced with passive rock bolts under plane failure.
