摘　　要：大跨径隧道浅埋段软弱围岩具有强度低、稳定性差等特点,在隧道施工中易引发大变形、崩塌等现象,严重影响了隧道施工和安全。文中以某大跨径隧道软弱围岩浅埋段为研究背景,依据现场监控量测信息,并结合施工工序,综合分析了其变形特性,以期为类似隧道施工变形控制提供参考。Due to the characteristics of low strength and poor stability,the weak rock surrounding the shallow buried sections of large-span tunnels often leads to significant deformations,collapses,and other phenomena during tunnel construction,which seriously affects construction progress and safety.Based on on-site monitoring and measurement information and the construction processes,this study comprehensively analyzes the deformation characteristics of the shallow buried sections of a large-span tunnel surrounded by weak rock.The research findings can provide reference for deformation control in similar tunnel construction.
