摘要
锚喷支护是加固水电工程地下室围岩、保障硐室安全的重要手段。根据江垭地下厂房工程实践 ,对常用的砂浆锚杆 (含超长锚杆 )和喷射混凝土支护工程 ,采取了若干施工技术和质量控制措施 ,取得了较好的效果。
Shotcrete and rockbolts is an important method to reinforce the underground tunnel surrounding rock and ensure the stability of underground tunnel. The engineering practice in the underground powerhouse construction of the Jiangya project has proved that, by means of some construction techniques and quality control, the support engineering of routine mortar rockbolts and shotcrete is successful.
