摘要
岩锚梁是地下厂房开挖施工中难度最大、质量要求最高的部位,岩锚梁开挖成型的质量将直接影响到厂房岩壁吊车的运行安全。针对官地地下厂房以玄武岩为主、节理较发育、岩石较硬,采用了"岩锚梁分序开挖"和"岩台双光面爆破"的施工方法,取得了好的成型效果。
Rock-anchored beam,with the highest quality requirement,is the most difficult part in underground powerhouse excavation.The quality of the beam will directly affect the operation safety of the crane in the power house.According to the basalt dominated characteristic together with its developed joints and hard rock conditions of Gongdi underground powerhouse,Sub-sequence Excavation Method and Both Smooth Rock Side Blasting Method are applied and have significant molding effect.
