摘　　要：锚杆进行巷道支护的过程中,不同的锚杆支护参数对支护的效果具有不同的影响。基于此,采用仿真分析的形式对不同锚杆预紧力及锚杆安装角度作用下的应力场进行分析。分析结果表明,保持足够的预紧力及较小的安装角度能够发挥锚杆的支护作用,提高巷道围岩的稳定性。In the process of anchor rod for roadway support,different anchor rod support parameters have different effects on the effect of support.The stress field under different preloads and installation angles was analysed in the form of simulation analysis,and the results showed that keeping sufficient preloads and small installation angles can play a role in the support of anchor rods and improve the stability of the roadway surrounding rock.
