| 摘 要： | 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. |
| 关 键 词： | 压力型锚索 岩体 梯度变化 力学性质 |

| Abstract: | In order to study the anchor mechanism of cable more precisely,the stress state of the pressure type cable system was simulated by FLAC3D software,the mainly focus on rock which had changed mechanical properties surrounding the hole wall.And the compressive stress around the wall,the rule of shear stress distribution could be obtained,the results were verified to practical engineering. |
| Keywords: | pressure type cable rock mass gradient change mechanical properties |
