摘　　要：随着交通基础设施建设的不断推进,小净距隧道施工面临着诸多挑战。基于猴屿隧道项目,研究小净距隧道双侧壁导坑法施工下的围岩变形与压力分布规律,并对施工过程中围岩压力和变形进行监测。监测结果表明:在双侧壁导坑法施工过程中,不同开挖区对围岩压力与变形产生显著影响。With the continuous advancement of transportation infrastructure construction,the construction of small clearance tunnels is facing many challenges.Based on the Monkey Island Tunnel project,this study investigates the deformation and pressure distribution of the surrounding rock during the construction of a small clearance tunnel using the double-sided wall guide method,and monitors the pressure and deformation of the surrounding rock during the construction process.The monitoring results indicate that different excavation zones have a significant impact on the pressure and deformation of the surrounding rock during the construction process of the double-sided wall guide method.

关 键 词：双侧壁导坑法 围岩压力 变形分析
