摘要
采用数值分析软件 ANSYS建立 3D模型 ,分析了锚杆的横向作用机理 .用对比方法分析了加锚非连续岩体与锚杆的错动变形和受力规律 ,模拟了加锚非连续岩体变形过程 ,获得了非连续岩体与锚杆的相互作用规律以及非连续岩体和锚杆的变形规律 .研究发现了剪切时锚杆起“导轨作用”的特殊现象 ,指出其对非连续岩体的稳定性有负面影响 .
By using 3D ANSYS software, the transverse action mechanism of rock bolts in discontinuous rock mass was analyzed. The deformation process of discontinuous rock mass restricted with a rock bolt was simulated. The laws of interaction between a rock bolt and rocks and the displacements of discontinuous rock mass and a rock bolt were gained. An unusual characteristic phenomenon of a rock bolt, called “the railway function” of rock bolt, was discovered in shearing. This function is harmful to the stability of discontinuous rock mass by rock bolting.
