摘要
柔性注压锚杆是一种新型锚杆,通过简化其力学模型,采用有限元方法模拟,分析了锚杆壁厚、钢丝位置、钢丝直径、橡胶材料以及围岩对锚杆强度和围岩与锚杆接触压力的影响,给出了一定结构参数下的最优结果。
Flexible pressurized anchor is a kind of new anchor. Mechanical model for the anchor was established. With the finite element method, we study the influences of the anchor section thickness, location of steel wire, diameter of steel wire, rubber material and the surrounding rock on the anchor strength and the contact stress. The best result of the anchor optimization under some parameters is gained.
