摘要
为了提高巷道安全性、降低后期维修难度、减少支护成本,使用控制变量的方法,研究了不同长度锚杆、不同间排距锚杆对巷道围岩变形的影响,从而充分发挥锚杆支护效果,保障巷道的安全。
In order to improve the safety of tunnels,reduce the difficulty of later maintenance,and reduce support costs.The method of controlling variables is used to study the influence of different lengths and spacing of anchor bolts on the deformation of the surrounding rock of the tunnel,in order to fully utilize the support effect of anchor bolts and ensure the safety of the tunnel.
