岩体加锚的物理力学效应非常明显。利用理论分析和界面元数值模拟研究了锚杆对岩体内聚力、内摩擦角值的影响,讨论了不同的锚杆倾角及密度对岩体内聚力、内摩擦角值的影响程度。在此基础上,给出加锚后岩体等效内聚力的近似计算式。
It is very obvious for the rock mass physical-mechanical effect because of anchor reinforcement.The influence on rock mass cohesion and internal friction angle because of rock bolting is studied and the difference for angle and density of rock bolting is discussed used theoretically and interface element numerically method.Based on this,the calculating formula of equivalent cohesion of anchored rock mass is given.
