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。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.
