摘要
单纯锚杆支护不能防止围岩的风化 ,不能有效控制杆间岩石的剥落 ,通常在围岩松动或大变形的情况下 ,导致锚杆支护的失效。采用光面爆破、喷射混凝土、金属网、钢带等配套技术 ,可改善锚杆支护的性能。
The mating technology such as smooth blasting,jet concrete,wire netting and steel band were used to improve anchor bar supporting property.The authors systematically discussed the development and application about various mating technology of anchor bar support.
