ON FUZZY ASYMPTOTIC THEORY BASED RELIABILITY ANALYSIS FOR SLOPE PROGRESSIVE FAILURE

  • 摘要: 研究边坡的渐进破坏过程对边坡稳定性的影响,认为边坡破坏是由局部向整体扩展的渐进过程,它具有随机性和模糊性双重特性。渐进破坏模糊随机法能很好地反映边坡体内局部破坏的产生、扩展及对边坡整体可靠性的影响。基于岩土体的空间变异性,考虑了随机变量和极限状态函数的模糊性,以模糊随机变量为基本变量建立了边坡渐进破坏的模糊极限状态方程,计算边坡局部破坏和扩展破坏的模糊概率,进而得出渐进破坏模糊概率。算例研究表明,基于模糊随机理论的边坡渐进破坏分析方法,更能反映边坡稳定的实际状态,为边坡的可靠性分析提供了一条新的思路,更有待于进一步的研究和探索。
