摘    要: 倾倒变形破坏常见于层状岩质边坡工程,其机理研究对边坡稳定性分析具有重大意义。在国内外相关研究基础上对弯曲倾倒、块状倾倒及块状弯曲倾倒3种不同破坏模式进行了分析,就边坡几何形状、岩层强度和长细比、层面力学参数、地下水、开挖作用等因素对倾倒变形的影响进行了阐述,介绍了倾倒变形破坏机理在物理模型试验、极限平衡、数值模拟3种方法中的研究进展,指出了不同方法的适用性和优缺点,说明了研究中需要改进和深化的内容。

关 键 词:倾倒变形  破坏机理  层状边坡  数值模拟

Abstract:Toppling deformation failure is common in layered rock slope projects.It makes sense to research on toppling failure mechanism in slope stability analysis.On the basis of the relevant research both at home and abroad,three main different failure modes of toppling deformation are analyzed.They are flexural toppling,block toppling and blockflexure toppling.Influential factors of toppling deformation like the geometrical shape of slopes,rock strength and the ratio of length to thickness for layers,mechanical p...
Keywords:toppling deformation  failure mechanism  layered slope  numerical simulation
