摘要

应用力学手段研究顺层岩质边坡失稳机理以及顺层岩质边坡稳定与其刚度密切相关在该领域获得了较多研究者认可，力学分析也成为顺层岩质边坡稳定研究的重要手段之一，在顺层岩质边坡刚度对其稳定的影响获得广泛的关注同时，却未能有人专门研究其刚度与其破坏特性之间的关系，为此在总结前人研究成果基础上，采用柔度作为其刚度指标，认为顺层岩质边坡破坏力学模型、破坏形态以及临界长度与其柔度大小密切相关，在其柔度小于临界柔度值时，可简化为杆模型，在其柔度值大于其临界柔度值时，根据其实际坡长，可简化为梁或杆模型，并分析了柔度大小与其破坏特征之间的关系，指出溃屈破坏一般只在特定的情况下发生。

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.
