压力型锚索锚固段的受力分析

Mechanical analysis on anchorage segment of pressure-type cable

根据压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。在此基础上讨论了锚固体、岩土体及其界面的力学参数对剪应力和轴力分布的影响,从而得出了一些有意义的结论,为该类锚索设计和计算以及新型锚固技术的开发和应用提供了一种理论依据。

Based on the mechanical conditions of the anchorage segment of the pressure-type cable, the solutions for distribution of the shear stress and the axial force in a pre-stressed cable are derived. The influences of the mechanical characteristics of the anchorage segment and their interface with the rock mass on the shear stress and the axial force are discussed. Some conclusions are obtained and provide a theoretical basis for designing and calculating of the pressure-type cable.
