摘　　要：在盾构隧道设计中,若盾构衬砌接头设计不合理,则会极易造成隧道渗水、局部破损、爆裂等现象,从而影响整个隧道的正常使用。论文围绕盾构衬砌接头的主要破坏形式、应力分布状态进行了分析,并采用经验公式和数值模拟的形式两相对照,其匹配度良好,给出了合理的配筋设计建议。In shield tunnel design,if the joint design is not reasonable,it will easily cause tunnel seepage,local damage,burst and other phenomena,thus affecting the normal use of the whole tunnel.The main failure modes and stress distribution states of shield lining joints are analyzed,and the empirical formula and numerical simulation are used to compare the results.the matching degree is good,and the reasonable design suggestions of reinforcement are given.
