摘　　要：随着城市基础设施的快速发展,盾构法作为现代轨道交通重要的施工方式,不可避免会对周边建构筑物产生相应的影响。以flac3d数值模拟技术为工具,模拟盾构隧道在下穿排水箱涵时的完整施工过程,重点分析了盾构施工中隧道形变的发展规律,探讨了隧道施工过程对排水箱涵结构变形产生的具体影响。结果显示,在盾构施工过程中排水箱涵结构变形稳定性控制在安全范围内,为今后类似工程提供了理论依据和参考数据。With the rapid development of urban infrastructure,shield tunneling has emerged as a key method in modern rail transit construction,inevitably affecting adjacent buildings and structures.Employing FLAC3D numerical simulation method,the entire construction process of shield tunnels passing beneath drainage culverts were simulated.The main focus of this study lied in analyzing the deformation pattern changes at monitoring points during the shield construction and investigating the specific impact of tunnel construction on drainage culvert structures.The findings reveal that the deformation stability of drainage culvert structures remains within a safe range during shield construction,thus providing theoretical support and reference data for similar projects in the future.
