摘要
基于弹塑性时论理论研究了围岩与锚杆支护互馈作用机制,分析了支护对巷道围岩应力状态的影响,研究表明锚杆支护阻力对巷道围岩的应力应变状态有较大影响,通过调整锚杆支护阻力可以改变围岩的应力状态,保证巷道安全稳定。
The feed mechanism of surrounding rock and bolt supporting was studied based on the theory of elastic-plastic theory. The research shows that the support resistance has a great influence on stress and strain state of surrounding rock, by adjusting the resistance of the bolt support can change the stress state of surrounding rock and ensure security and stability of roadway.
