摘要: 根据极限平衡理论,结合悬臂梁模型,提出了一种简易的岩土复合的滑动-弯曲倾倒破坏的理论分析方法。利用库伦土压力理论分析了上覆土体对 下卧岩层的作用力,结合悬臂梁模型和协调平衡原理,引入重度增大系数,求得了下卧反倾层状软岩在上覆土体作用力下的稳定安全系数的解析表达式。 结合实例验证了所提方法的正确性。所给出的理论分析方法有益于快速判断此类边坡的稳定性。

Abstract: Based on the limit equilibrium theory and the cantilever beam model, a simple theoretical analysis method for toppling failure of rock and soil composite structures was proposed. Firstly, the force on the lying rock from the overlying soil was analyzed, according to Coulomb’s earth pressure theory and Tan wall theory. Secondly, with flexural cantilever model and coordinate the equilibrium equation, increasing factor of weight was introduced, and the analytic expression of the stability safety factor for anti-inclined and layered slopes with rock and soil composition was solved. At last, a case study was used to verify the correctness of the proposed method. The presented theoretical analysis method is beneficial to judge the stability of this kind of slopes quickly.

Key words: geotechnical engineering, anti-inclined slope, rock and soil composition, flexural toppling, stability analysis
