摘　　要：以重庆滴水岩2号隧道洞口WY2危岩加固为核心,对临崖陡坡危岩加固处理技术进行详细分析,主要针对危岩开挖、修整、支护、加固等问题形成成套施工工艺,同时采用危岩打设锚杆、十字锚头加固等安全防护措施,以保证结构安全稳定。With the development of the economy, infrastructure construction gradually becomes more diversified, and the difficulties and challenges faced by urban tunnel infrastructure construction are gradually increasing. Dangerous rock reinforcement treatment technology is analyzed in detail, and a complete set of construction technology is formed for the excavation, repair, support, and reinforcement of the dangerous rock. At the same time, safety protection measures such as anchor rods and cross anchor head reinforcement are adopted to ensure the structure. safe and stable.Hope to provide theoretical guidance for follow-up similar projects through the research content of this thesis.
