采用ANSYS有限元软件,建立了加锚节理岩体的三维数值分析模型,当锚杆的横向导轨作用发生时,对其受力及形变特性进行了深入分析。研究结果表明,两节理附近锚杆承受剪切相反的扭转力矩的作用,节理处也是其最大剪应变分布区;节理两侧锚杆存在上下拉压相反的轴向应力及应变;模型前后方向锚杆产生均衡的作用力及均衡应变。

By using ANSYS numerical analysis software, a 3D model was built and mechanical properties of bolt under its railway effect were achieved. The regions of bolt near joint are subject to torque caused by opposite shear forces, and are distributed the maximum shear strain. As to axis,tension and compress stress are concentrate in the up and down area of the same regions. Balanced stress and...
