摘　　要：拉力型锚索作为岩土工程中重要的锚固结构,其受力特征的研究对于岩土锚固工程的安全稳定具有重要意义。根据拉力型锚索锚固段受力状态,导出了锚固段剪应力和轴力分布的理论解。在此基础上讨论了围岩体弹性模量与注浆体当量弹性模比、锚固体半径、轴向拉拔荷载等因素对剪应力及轴力分布的影响,得到了其在不同条件下的应力分布变化规律以及对结构的影响,为该类锚索锚固工程的设计和施工提供理论依据。The tension-type anchor rod is a critical anchoring structure in geotechnical engineering,and the investigation of its load characteristics is essential for ensuring the safety and stability of geotechnical anchoring projects.By analyzing the load state of the anchoring section of the tension-type anchor rod,a theoretical solution for the distribution of shear stress and axial force has been derived.Building on this foundation,the effects of various factors,including the elastic modulus of the surrounding rock mass,the equivalent elastic modulus ratio of the grouting material,the radius of the anchoring body,and the axial tensile load,on the distribution of shear stress and axial force have been examined.The study reveals the variation patterns of stress distribution under different conditions and their impact on the structure,thus providing a theoretical basis for the design and construction of such anchor rod anchoring systems.
