摘　　要：深部高应力软岩巷道围岩具有大变形、大地压、长时间持续流变等特性,采用传统的锚杆支护材料很难有效地控制这类巷道围岩变形。因此,设计了一种新型高强让压螺纹钢注浆锚杆,实现了围岩卸压与注浆锚固双重功能,提高了围岩的锚固效果,有效地保持了巷道的稳定。Due to characteristic of deep and soft rock roadway with large deformation,high stress and continuous creep deformation,traditional bolt materials are facing difficult in control of these roadways.Therefore,a new high strength and yield rebar grouting bolt was designed,which achieves double functions of rock pressure relief and grouting.Anchoring effect of surrounding rock is strengthened,and stability of roadway is maintained effectively.
