考虑不同拉压特性的边坡岩体结构稳定性位移判据

Displacement Criterion of Structure Stability for Rock Mass Slope by Considering Different Tensile Compressive Behavior

岩体顺层边坡破坏主要表现为剪切滑动和溃屈破坏等形式，而溃屈破坏常具有以板或梁的形式发生屈曲破坏的特征，其是否发生屈曲破坏与岩体力学性态有很大的关系。在已有研究成果的基础上，针对岩体拉压特性不同的特点，探讨了顺层边坡岩体结构的屈曲稳定性态，并对岩梁模型进行了合理修正，给出了顺层边坡岩体结构稳定性位移判据。

The failures of the bedding slopes for rock mass mainly display the shearing slip and buckling failure, the buckling failure often has the characteristic of the buckling failure of beam or plate. Whether budding failure takes place is relative to mechanical behavior of rock masses. Based on current research results, the buckling behavior of structural stability for bedding rock slope is studied in accordance with the different tensile compressive characteristics of rock masses,and the model of rock beam is reasonably modified. The displacement criterion of rock structure stability is given for bedding rock slope.
