摘要： 在对拱肩槽自然边坡工程地质条件详细调查的基础上，采用工程地质宏观分析和数值计算相结合的研究手段，对拱肩槽人工边坡整体稳定进行了系统研究；通过结构面组合分析，提出了人工边坡可能出现的块体失稳模式；从块体稳定性影响因素入手，建立了块体稳定性评价标准，并评价了块体的稳定性。工程地质宏观分析表明：拱肩槽边坡整体稳定性较好，数值模拟计算结果显示人工边坡变形特征不突出、稳定系数较高，人工边坡可能出现的块体多处于基本稳定状态。研究成果为工程设计与施工提供了重要依据，并对类似工程提供了可借鉴的经验。

Abstract: Based on detailed investigation on the engineering geological conditions of the natural slope at the right abutment of Wudongde hydropower station on Jinsha River, the global stability of artificial slope was analyzed systematically by means of macro-analysis and numerical calculation. Potential instability model of artificial slope block was given via structural plane analysis. Starting with the influencing factors of block stability, an evaluation standard was established, based on which the block stability was evaluated. Engineering geological analysis showed that the global stability of artificial slope was good. Three-dimensional discrete element simulation results showed that the artificial slope displayed inconspicuous deformation characteristics. Most of the potential blocks of artificial slope were generally stable. According to global and local stability analysis, reinforcement measures were put forward for the slopes. The research provides a basis for the design and construction and for similar projects.

Key words: engineering geology evaluation, 3-D discrete element, block, instability mode analysis, stability evaluation standard
