摘　　要：随着城市基础设施的迅速发展,盾构隧道作为一种重要的交通构建方式越来越受到重视,管片接头受力性能是影响盾构隧道衬砌结构设计参数的关键因素,而采用新型连接件的接头受力性能尚不明确。本文参考国内外盾构隧道衬砌快速连接件的研究和应用情况,基于新型快速连接件的受力性能,依托某地铁区间隧道,通过有限元数值模拟,获得衬砌结构设计接头抗弯刚度参数,通过同济曙光-盾构隧道计算分析软件结合计算结果建立了基于梁-弹簧法的三环错缝分析模型,分析其内力分布特征,该连接件符合规范要求。With the rapid development of urban infrastructure,shield tunnels as an important means of transportation construction are increasingly valued.The mechanical performance of segment joints is a key factor affecting the design parameters of shield tunnel lining structures,yet the mechanical performance of joints using new types of connectors remains unclear.This paper refers to the research and application of rapid connectors for shield tunnel linings at home and abroad.Based on the mechanical performance of new rapid connectors and relying on a subway tunnel section,finite element numerical simulation is used to obtain the bending stiffness parameters of the lining structure design joints.Combined with the calculation results from Tongji Dawn-Shield Tunnel Analysis Software,a three-ring staggered analysis model based on the beam-spring method is established to analyze its internal force distribution characteristics.The connector complies with the specifications.
