摘要
通缝、错缝管片在国内盾构隧道施工中均有运用,关于两种衬砌形式孰优孰劣的争论一直存在。基于两种衬砌的结构特征,采用修正的地层弹簧模型,结合南京地铁一号线的工程实例,对通、错缝拼装隧道衬砌使用阶段的受力及变形进行了对比分析。得出了一些有益的结论,为设计施工提供参考。
Both continuous- jointed segmental lining and stagger- jointed segmental lining are used in shield driven tunnels. Which kind of segmental lining is better is still a question. Due to structural characteristics of the linings, based on the project of Metro line No. 1 in Nanjing, the internal forces and displacements of the two kinds of lining during their construction are compared by using ground spring model and boundary value method.
