摘要
介绍了盾构法隧道装配式衬砌管片接头形式的分类,以及对管片接头进行模拟的接头模型,并归纳了研究接头模型的接头刚度的影响因素,最后指出运用有限元工具对接头进行精细化研究、探求接头尺寸效应对接头刚度影响的可行性与必要性。
This paper introduces the category of joint in shield tunneling assembled linging, and details the devdopment of joint model in analy sis. Then it also sums up the influence factors of joint stiffness. Lastly, refined researches for joint with FEM method are indicated and its lea sibility and effectivity is mentioned in size effect of the segment joint.
