| 摘 要： | 针对盾构隧道错缝拼装的特点，提出了一种新型的错缝拼装环间接头模型，并给出了模型中参数的确定方法与取值范围。利用该模型建立了盾构隧道错缝拼装管片结构受力分析的拟三维仿真模型，分析了上海某过江输水隧洞的通水运营工况，结果表明，错缝拼装衬砌比通缝拼装结构的相对变位要小，结构内力值要大，环间接头模型可以较好地反映错缝拼装在隧道三维工作状态中的约束作用。

| Abstract: | A new model of joints between lining circle is proposed according to the characteristics of stagger-jointed assembling shield tunnel.The method of ascertaining the parameters and the range of the parameters are given in this paper.Using this model,a qusi-3D simulation model is obtain to analyze the internal force of segmental linings in stagger-jointed assembling.The operation stage of a water diversion tunnel in Shanghai is analyzed,which indicates that the stagger-jointed assembling structure is less than... |
