摘要:: 在对大渡河左岸某大型堆积体的物质组成及结构特征、成因机制分析的基础上，恢复岸坡原始地形地貌，以此建立了地质原型。根据岩体中最为发育的垂直节理面以及层面来划分单元，建立大约6 000多个单元，滑体以下的滑床基岩部分作为固定单元处理。采用离散单元法对堆积体运动过程中各演化阶段进行模拟，由此得出堆积体的演化过程划分为滑移－拉裂、碎屑流两个阶段，其成果与定性判断相吻合。

Abstract:: Based on the analysis of material composition and structure characteristic,genetic mechanism in Dadu River left bank some large-scale stack body,the bank slope initial form landform restores and the geological prototype is established.More than 6000 units are set up according to the vertical divisional plane as well as the stratification plane.The slip-sliding below the bed rock takes the fixed unit to deal with.Using the Distinct Element Method to simulate each evolved stage in accumulation of body movement process,the results showed accumulation of body evolutionary process divide into the slipping-tension fracture and the detritus flows two stages with the results and qualitative judgments coincided.
