摘　　要：首次采用非连续变形分析 (DDA)法 ,对采动岩体结构中的“三咬拱”结构模式、形态、位移与关键层等进行动态模拟 。This paper, for the first time, adopts the Discontinuous Deformation Analysis (DDA) to model respectively the structural patterns, forms, displacement and key stratum (dynamic modeling) for Arches with Three Grips and Grip Beams in excavated rockmass, and some significant conclusions are drawn out.

关 键 词：采动岩体 三咬拱 DDA 动态模拟 结构模式 形态 位移
