摘　　要：基于弹塑性理论研究及现场深基点位移观测 ,对岩体锚固的承载结构体系作了深入探讨。提出了岩体锚固的承载结构体系由关键承载结构、次生加固承载结构和准塑性承载结构组成的概念 ,并分析了三者之间的相互作用关系。为工程应用 ,籍助顶板深基点位移观测 ,给出了各结构范围的工程界定。Based on elastic and plastic theory and displacement observation of in-situ interior rocks, the supporting system of rock bolting system is deeply analyzed. A concept is provided that the supporting construction of rock bolt system consists of key, secondary reinforcement and quasi-plastic supporting structures. And their interactions are analyzed. Engineering definitions of the extent of various structures are given for engineering applications based on displacement observation of the roof abscission layer. Finally the principle of engineering definition is described in terms of its instructive significance for engineering practice.
