摘　　要：文中以杭州博奥隧道盾构施工工程为工程背景,结合工程特点和地质条件,采用梁-弹簧模型进行管片内力及变形分析计算和ANSYS软件对盾构隧道进行整体纵向计算分析,根据计算结果分析得出工程设计是否规范,并提出对应的安全隐患提出控制措施,以达到工程施工期间安全、经济、高效的目标。Taking the Hangzhou Boao tunnel shield construction project as the engineering background,combined with the engineering characteristics and geological conditions,the beam-spring model is used to calculate the internal force and deformation of the segment and the ANSYS software is used to perform the overall longitudinal calculation and analysis of the shield tunnel.According to the calculation results,this paper checks out whether the engineering design is standardized,and puts forward the corresponding safety hazards and control measures to achieve the goal of safety,economy and efficiency during the construction period.
