摘要

针对顺层岩质边坡,概括出实际边坡工程中常见的几种破坏形式,以其地质背景及力学作用机制为依据,抽象出了不同约束条件下岩梁结构简化分析模型。利用梁板屈曲理论,讨论了岩梁变形的前屈曲状态和后屈曲状态的分叉特性,建立了岩层结构发生灾变的判据。利用文中理论方法及所建立的位移判据,并结合工程现场有效的量测手段,可方便、有效的判定岩质顺层边坡的稳定性。
To the bedding rock slope,several common failure forms in slope engineering are summarized. According to the geologic background and the mechanical mechanism,this paper extracts the rock beam structure model under various restriction. On the basis of buckling theory of beam and board,the catastrophic criterion of the structural deformation and failure of rock mass is established by studying buckling stability and bifurcating behavior of the rock beam under various restriction. The displacement criteria given in the paper and the available measure method in engineering locale are used to predict the stability of the rock slope conveniently and efficiently.
