摘　　要：为了保证盾构隧道衬砌结构的安全性,通过工程试验数据,利用均质圆环法和梁-弹簧模型,对比分析了考虑管片环向接头刚度与否对衬砌结构力学特性的影响;并对环向接头刚度值的大小对衬砌结构力学特性的影响做了分析,得出了矩形盾构隧道衬砌结构的内力和位移随环向接头刚度值的变化规律,同时利用工程试验数据与仿真结果作了相互映证。In order to ensure the safety of shield tunnel lining structure,the homogeneous ring method and beam spring model are used to comparatively analyze the result of whether considering the segment joint stiffness influence on the mechanical properties of lining structure with the engineering test data.After that the influence of the stiffness value on the mechanical properties of the lining structure is analyzed in depth,and the law that the internal force and displacement of the lining structure changes with the change of the ring stiffness is concluded.At the same time,the test data and simulation results are reflected by the interaction of each other.
