摘　　要：根据Mindlin问题位移解、弹性力学等理论,导出了压力分散型锚索锚固段弹性黏结应力和轴向应力分布表达式。采用岩质边坡工程的参数,对锚固段的应力分布进行计算,总结了岩质条件下锚固段应力分布特点,这对压力分散型锚索理论的进一步研究和设计计算提供了理论依据。According to Mindlin＇s solution of displacement and the theory of elasticity mechanics,the elastic formulas for distributions of shear stress and normal stress on bonded length of pressure-dispersive cable was derived.Parameters of rock slope were used to calculate the stress along the length of anchoring segment.Stress distribution feature of the anchoring segment was obtained.It is useful for further study on the theory and design calculation of the pressure-dispersive cable.
