Abstract: The mechanical analysisis an important means for studying failure mechanism of bedding rock slope. Stiffness is strong effects on is to stability greatly. The paper brings forward some viewpoints based on summarizing the existed works. Adopting flexibility to measure stiffness of bedding rock slope, we can achieve the relation between mechanical model, failure character and critical slope length of bedding rock slope. If the value of flexibility is smaller than critical flexibility, bedding rock slope can be simplified to pole model. If the value of flexibility is greater than critical flexibility, bedding rock slope can be simplified to pole or girder model according to actual slope length; and buckling failure of bedding rock slope happens only under special condition.

Key words: bedding rock slope, Stiffness, flexibility
