摘要

盾构法以其施工速度快、经济效益高、安全性好等特点被广泛应用于隧道施工,在联络通道的应用也必将越来越广泛,但目前对于小直径盾构隧道刚度有效率的研究相对较少,以天津某盾构法联络通道项目为例,用ABAQUS建立多种隧道及管片的数值计算模型,研究小直径隧道刚度有效率的大小及影响因素。结果表明:(1)联络通道的刚度有效率与普通隧道的刚度有效率差别不大,纵向刚度有效率在0.07左右,横向刚度有效率在0.5~0.6之间,横向刚度提升对纵向刚度有正向关系;(2)管片拼装方式对纵向刚度有效率影响不大,对于隧道变形影响较大,通缝拼装下发生了极为不对称的变形;(3)螺栓预紧力的改变会影响衬砌环环间张开量,对纵向刚度有效率有一定影响,但对横向刚度有效率影响不大。

Abstract

Shield method is widely used in tunnel construction due to its high construction speed, high economic efficiency and good safety characteristics, and the application of communication channels will also become increasingly widespread. However, the research for small-diameter shield tunnel stiffness efficiency is relatively limited. Based on a shield method contact channel project in Tianjin, with ABAQUS to establish a variety of tunnel and segment numerical calculation model, study the size of small diameter tunnel stiffness efficiency and influencing factors. The study found that: (1) The stiffness efficiency of the contact channel is not different from that of ordinary tunnel, the longitudinal stiffness efficiency is around 0.07, the transverse stiffness efficiency is between 0.5 and 0.6, the transverse stiffness improvement has a positive relationship on the longitudinal stiffness; (2) The segment assembly method has little influence on the efficiency of longitudinal stiffness, and extremely asymmetric deformation under the joint assembly; (3) The tension of the bolt, which has some influence on the efficiency of the longitudinal stiffness, but has little influence on the efficiency of transverse stiffness.
