摘　　要：基于Kelvin位移解,根据拉力型锚杆实际工作状态,推导出拉力型锚杆锚固段轴向应力和剪应力分布的理论解,并分析拉力型锚杆的受力特点,为拉力型锚杆的力学分析和设计提供理论依据。在此基础上讨论张拉荷载、孔径、外界岩土体弹性模量对锚固段轴力与剪应力分布的影响,并得出了一些有意义的结论。Based on Kelvin displacement solution,theoretial; sion-tpye anchor was derived based on the practical work condition of anchor. The analysis of stress features of tension- type anchor provided a theoretical basis for its mechanical analysis and design. On this basis, the influence of tensile load, aperture, modulus of elasticity for rock and soil on axial stress and shear stress of anchorage segment of tension- type anchor were discussed, reaching some significant conclusions.
