摘　　要：采用多层次喷浆钢丝绳与锚杆、注浆锚杆,均匀、不同深度地置入围岩中,使单位岩体内的锚杆组合量的密度加大并多次注入带压浆液胶结强化围岩体;重造支护组合体,实现以围岩为支护依托和参与体,主动控制和抵御深部围岩应力。Multi-layered shotcrete steel wire ropes, anchor rods and grouting bolts are placed evenly in the surrounding rock at different depths. The density of the bolt combination in the unit rock body is increased and multiple times with pressured slurry cementation is injected. Strengthen the surrounding rock masses; reconstruct the support and support structure, realize support and participation with surrounding rock, and actively control and resist the deep surrounding rock stress.

关 键 词：多层次锚杆 稳压胶结 构建均质同性围岩 支护圈体
