摘要：
锦屏二级水电站地下厂房岩锚梁地质条件较差,岩锚梁开挖过程中采取了沿保护层深孔预裂、分区开挖,在斜台下部增加锁口锚杆、用高强树脂锚杆超前支护、超前灌浆等多项有效技术措施,岩壁梁施工取得了良好的效果。
Abstract：As the geological condition for the rock anchored beam of the underground powerhouse of Jinping-II Hydropower Station is poor,the effective construction measures such as deep hole pre-splitting and zoning excavation along the protected layer,adding locked anchor-bars at the lower part of the declined table,advanced supporting with high-strength resin anchor-bars,advanced grouting etc.are adopted therein,and then better construction effect is obtained as well.
