摘　　要：根据挖动岩体结构特点，首次建立挖动岩体中普遍存在的自然咬合拱、隧洞咬合圈、采场咬合梁、采场三咬拱、采场底板突水反三咬拱以及边坡咬合岩块等多种自然结构（ 非人工结构） 模型。并通过结构分析，得出前述咬合岩块结构的自由度 Ｗ＝ ０ ，，亦即，这些结构均为稳定静定结构。同时， 阐述了挖动岩体结构模型特点及挖动岩体力学研究方面的若干进展。Based on structure character of excavated rockmass,various generally and naturally existing (no artificial) structure models,including natural grip arches,grip rock rings around tunnels,grip beams in longwall face,grip arches with three-grips,reverse grip arches with three-grips in water-inrush from floor,grip rock blocks in slopes,etc.,were constructed.By analyzing the structures,it was found out that the above grip structures are all stably statically determinate,with their freedom degree for rock blocks being W=0.Characteristics of structure models in excavated rockmass and recent developments of research in excavated rockmass mechanics were also discussed.
