摘要
为了更加精确地研究岩体风化程度对锚索锚固效果的影响,采用FLAC3D软件对风化岩体中压力型锚索锚固段的应力状态进行了数值模拟研究。随着风化岩体的力学性质按线性函数梯度变化,重点分析了风化岩体线性变化的力学参数对锚索孔内注浆体的压应力和接触面上的剪应力的影响,使锚索锚固机理的数值模拟研究成果更好的服务于实际工程。
Studying on the anchor mechanism of cable affected by weathering degree precisely, the stress state of the pressure- type cable in weathered rock mass was simulated by FLAC3D. As elastic modulus, Poisson＇s ratio, cohesion, internal friction angle of weathered rock changed with exponential function, the compressive stress of anchor cable holes grout and the rule of shear stress distribution around the contact surface were analyzed to enable the research results of anchor mechanism numerical simulation to be better applied in the practical engineering.
