盾构法隧道衬砌结构由若干管片通过各种连接件 (如螺栓等 )拼装而成 ,因此相邻管片之间存在接头。本文在讨论接头位置对衬砌结构刚度、周围土层抗力分布形式以及结构本身内力、变形等影响的基础上 ,试图对接头位置的优化提出一些建议 ,以期能给衬砌结构设计提供参考。
Shield tunnel lining structure by a number of pieces through a variety of connectors (such as bolts, etc.) assembled from the adjacent pipe between the joints. Based on the discussion of the influence of joint position on the stiffness of lining structure, the distribution of surrounding soil resistance and the internal forces and deformation of the structure itself, some suggestions are put forward to optimize the joint position in order to provide reference for lining structure design.
