摘　　要：通过分析矿山深部巷道围岩变形特征,包括:巷道顶板的变形破坏、角部破碎以及角部破碎;根据矿山深部巷道围岩变形的各种形式,进行矿山深部巷道围岩应力分布数值模拟;确定矿山深部巷道围岩应力应变关系,排除由于抗拉强度的不同导致对数值模拟造成的误差值;理论计算矿山深部巷道围岩应力分布,得出的矿山深部巷道围岩应力分布数值模拟结果,通过HISTORY命令设置变量来确定某处断面的位移变化和受力状态,判断模型是否达到平衡或者破坏状态。By analyzing the deformation characteristics of the surrounding rock in deep mine roadway,including:deformation and failure of roof of roof,broken corner and broken corner;according to various forms of deformation of surrounding rock in deep mine roadway,carry out numerical simulation of stress distribution of surrounding rock in deep mine roadway;The stress-strain relationship of the surrounding rock of the mine deep mineway excludes the error value caused by the difference in the tensile strength to the numerical simulation;the theoretical calculation of the stress distribution of the surrounding rock of the mine deep mineway results in the numerical simulation results of the stress distribution of the surrounding rock of the mine deep mineway.The HISTORY command sets variables to determine the displacement change and force state of a section,to determine whether the model has reached equilibrium or destruction.
