为了更加精确地研究锚索的锚固机理,通过FLAC3D软件对压力型锚索体系的应力状态进行了数值模拟。主要针对锚索孔壁周边力学性质梯度变化的岩体进行了研究,得到了周边岩体在轴向方向压应力、剪应力的分布规律,使锚索锚固机理的数值模拟研究方法更加符合工程实际。
In order to study the anchoring mechanism of anchorage cable more accurately, the stress state of the pressure anchoring cable system was simulated by FLAC3D software. The rock mass with the gradient of mechanical property around the hole wall of the anchor cable is mainly studied. The distribution rule of compressive stress and shear stress of the surrounding rock mass in the axial direction is obtained. The numerical simulation method of anchor cable anchoring mechanism is more in line with engineering practice .
