    摘要:

    西南地区广泛分布着堆积体组成的深厚堆积体边坡,堆积体边坡的稳定计算主要受堆积体的变形破坏模式和力学参数影响。结合雅砻江某水电站左岸某堆积体,分析确定该堆积体边坡边坡的边界条件和变形破坏模式;通过工程类比、室内试验及反分析法,兼顾各取值方法的差异和局限性,综合确定堆积体的强度参数。

    Abstract:

    The slope which is composed of deep accumulation body is widely distributing in southwest of China.The stability calculation of the accumulation body is mainly influenced by the deformation and failure mode and the mechanical parameters.A accumulation body on the left of a hydropower station which is located in YaLong river was used as an example.The boundary conditions and the deformation and failure mode of the accumulation body was analyed, and the strength parameter of the accumulation body was analysed by engineering analogy method、laboratory test method and inverse analysis method. Comprehensive determination of the strength parameter of the accumulation body consideration to the difference and the Limitation between these methods.
