MECHANICAL ANALYSIS OF APPARENT DIP BUCKLING MECHANISM OF STEEP STRATIFIED OBLIQUE ROCK: A CASE STUDY OF SHANYANG ROCKSLIDE IN SHAANXI PROVINCE

  • 摘要: 以陕西山阳滑坡为例,分析了陡倾层状斜向岩层岩质滑坡的视向滑动特征、滑移-溃屈破坏模式与机制。基于梁板理论、层状板裂结构岩体弯曲-溃屈破坏的力学模型在考虑自重、地下水静水压力作用及斜倾层状山体视向滑动侧向摩阻力作用的影响下,采用岩体结构力学分析的方法建立了相应的力学模型;经过力学分析,推导出基于斜坡自重、地下水静水压力与侧向摩阻力作用下的陡倾层状斜向岩层斜坡溃屈段长度条件方程。为验证条件方程的正确性,以山阳滑坡为例进行了验算,最后得出与实际调查较一致的结果,为防御陡倾层状斜向岩层斜坡产生视向溃屈破坏提供依据。
