通过极限荷载理论和强度理论分析,确定岩石锚梁构件的弹性极限荷载。对最小锚固深度进行限制。在此基础上,对岩石锚梁进行现场抗剪和拉拔试验研究,得到其相关力学性能。研究表明:锚梁构件的弹性极限荷载对初始缺陷比较敏感,施工中应严格控制;岩石锚梁的锚固深度在一定范围内对承载能力有较大影响,但是随着锚固深度的增加,岩石锚梁的承载能力逐渐趋于定值。 Based on the ultimate load theory and strength theory analysis, the elastic ultimate load of rock anchor beam components is determined. Limit the minimum anchoring depth. On this basis, the rock anchor beam on-site shear and pull-out test study, get the relevant mechanical properties. The research shows that the ultimate load of anchor beam is sensitive to the initial defects and should be strictly controlled during the construction. The anchorage depth of rock anchor beam has a great influence on the bearing capacity within a certain range, but with the increase of anchorage depth, Beam load capacity gradually tends to set value.
