摘要
本文假定岩壁吊车梁为刚体，根据岩壁吊车梁受力后的变位分析、考虑岩壁的弹性反力，建立比较接近实际的脱离体受力模型，推导出受拉锚杆轴向力的通用公式，并对锚杆、岩壁的变形和受力状态作全面的分析和控制。本文除对岩壁吊车梁的设计理论探讨外，并对锚杆的施锚和吊车梁的体形提出了改进意见。
Assuming the rock crane rail support to be a rigid body,the author in thepaper has established a more practicable free body model and derived a general formula tocalculate axial force of a tensile anchor bolt,taking into account the elastic counter forceof the rock wall based on the displacement analysis of the rock crane rail support afterloading,and analyze all-round the deformation and load bearing condition of bothanchor bolts and rock crane rail support.Besides the discussion on the design theory of rock crane rail support,The author alsopresents proposals to improve the construction of anchor bolts and the shape of rock cranerail support。
