摘要

为了对压力型锚索锚固段的受力进行更加精确的理论分析,通过法向集中力作用在横观各向同性半无限空间体内部柱坐标下应力的解析解,推导了力学参数(弹性模量和剪切模量)梯度变化(按指数函数变化)的风化岩体内压力型锚索注浆体在圆形均布荷载作用下受到的压应力和剪应力的理论解,可为压力型锚索加固设计提供一定的理论基础。
        In order to make a more accurate theoretical analysis of the stress of the anchorage section of the pressure anchor cable,the theoretical solutions of compressive stress and shear stress of the pressure anchor grouting body in weathered rock mass subjected to circular uniformly distributed load with mechanical parameters(elastic modulus and shear modulus)gradient change(according to exponential function change)are derived by the analytical solution of the stress in the column coordinates acting on the transverse isotropic semi-infinite space body under the action of the normal concentrated force,which can provide a theoretical basis for the design of pressure anchor cable reinforcement.
