Abstract：Based on the geological investigation on many bedding rock slopes，a slope classification system and eight types of failure modes with respect to bedding rock slope are presented. Furthermore，the analytical methods for stability of slip-fracture and slip-bending failure mode slopes are studied. It is pointed out that the stability analysis of the slip-fracture failure mode slope can be carried out by calculating the ultimate length of the unstable rock formation；slope reinforcement in advance or reinforcement and excavation simultaneously should be adopted to avoid slope failure for this kind of bedding rock slope. For the bedding slopes whose failure mode would be slip-bending due to the excavation of the rock mass along the bedding surface，the slope stability analysis should be introduced firstly by using the compressive elastic slab stability theory，and the step excavation height and reinforcement measures then could be determined. Water is the key factor inducing the failure of bedding rock slope，so the issue to ensure waterproofing and drainage must be considered in the slope design.
