为探讨锚杆在不同的安装角和预应力条件下对结构面强度和切向刚度的影响，进行了模拟实验研究·结果表明：锚杆安装角和预应力的大小对结构面强度和切向刚度有较大影响，加固结构面的剪切位移曲线具有明显的“塑性强化”性态，加锚后结构面的抗剪强度和切向刚度均有明显的提高，且加锚结构面抗剪强度的提高主要表现在结构面“等效粘结力”的提高，而结构面的“等效摩擦角”基本不变，加固结构面的剪切位移符合双曲线函数关系·最后对实验进行了有限元模拟，数值计算结果与实验结果具有较好的一致性
In order to investigate the influence of anchor bar on the strength and tangential stiffness of the structural plane under different installation angles and prestress conditions, the simulation experiment was carried out. The results show that the strength and tangential direction The shear-displacement curve of the reinforced structure has obvious “plastic strengthening” behavior. The shear strength and the tangential rigidity of the reinforced structure have obviously increased, The improvement of shear strength is mainly manifested in the improvement of “equivalent bonding force” of structural plane, while the “equivalent friction angle” of structural plane is basically unchanged, and the shear displacement of reinforced structural plane conforms to the hyperbolic function relationship. Finally, The finite element simulation is carried out. The numerical results are in good agreement with the experimental results
