| Abstract: | 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. |
