本文根据多层板裂结构岩体顺层边坡变形及溃屈破坏的特征,抽象出这种边坡的力学模型。以力学模型为基础,从结构失稳的观点出发,采用弹性力学理论和弹性稳定理论,建立了这种边坡的变形计算、溃屈稳定性分析以及溃屈破坏长度、深度预测的方法,说明了影响其溃屈稳定性的主要因素和预防这种边坡发生溃屈破坏的原则。最后,以某边坡实例验证了所建立方法的可行性。
In this paper, the mechanical model of the slope is abstracted according to the characteristics of the deformation and the failure of the layered slope of the multi-layered plate rock. Based on the mechanical model, from the viewpoint of structural instability, using the theory of elasticity and elasticity stability, this paper establishes a method for the calculation of slope deformation, the stability analysis of the collapse, and the prediction of the length and depth of the collapse failure. The main factors affecting the stability of its collapse and the principle of preventing the collapse and collapse of such slopes. Finally, the feasibility of the established method is verified by an example of a slope.
