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。
The ANSYS finite element software is used to establish a three-dimensional numerical analysis model of anchored jointed rock mass. When the function of transverse guide of anchor rod occurs, the force and deformation characteristics of anchor rock bolt are analyzed in depth. The results show that the anchor near the two joints is subjected to the torsional moment with the opposite shear force, and the joints are also the distribution area of the maximum shear strain. The axial stress and strain of the anchor on both sides of the joint are opposite; Rod produces a balanced force and equilibrium strain.
