摘要
在分析了松软巷道围岩破坏特征的基础上 ,证明锚固力的作用在于提高巷道周边破裂围岩的残余强度 ,并使之形成组合拱。探讨了锚固体强度和承载能力的理论计算问题。据此提出了松软围岩锚杆支护系统定量设计的方法 。
Based on the analysis of the damaged characteristics for the soft surrounding rock,it is proved that the function of the bolt reinforced strength depends on raising the residual strength of surrounding broken rock of roadway,and that the surrounding broken rock is made into a reinforced arch. The theoretical calculation for the strength and loading capability of the anchorage body is discussed.For the above reasons,the quantitative design method for the bolting system is proposed and proved by the field industrial experiment.
