摘要:
土层的剪切刚度和动力特性突变会导致隧道结构的动力响应改变,为揭示软土地区砂土夹层场地中盾构隧道的动力响应,以宁波轨道交通6号线盾构隧道穿越砂土夹层场地为研究背景,基于ABAQUS建立了盾构隧道三维土—结构动力相互作用有限元模型,考虑了盾构隧道管片接头处的非连续性,研究了土层和盾构隧道管片在不同地震强度荷载作用下的动力响应及接头的力学行为,结果表明:夹层场地加速度放大系数沿深度先减小后增大,隧道最大加速度出现在拱底;地震作用下衬砌连接处相互错动影响隧道内力分布,隧道拱肩、拱脚附近内力明显集中;接缝处变形程度分布不均,拱肩、拱脚附近接缝变形远大于其他部位;螺栓内力分布与接头变形程度有关,拱肩、拱脚处连接螺栓的内力较大。因此在盾构隧道抗震设计中要加强隧道拱肩、拱脚处的螺栓设计强度。
Abstract:
The sudden change of shear stiffness and dynamic characteristics of soil layer can lead to the change of dynamic response of tunnel structures. In order to reveal the dynamic response of shield tunnels in sandy interlayer site in soft soil area,taking the shield tunnel of Ningbo Metro line 6 crossing sandy interlayer site as the research background,a three-dimensional finite element model of soil-structure dynamic interaction of shield tunnel was es?tablished based on ABAQUS. Considering the discontinuity of shield tunnel segment joint,the dynamic response of soil layer and shield tunnel segment under different seismic intensity loads and the mechanical behavior of joint were studied. The results show that: The acceleration amplification factor of the interlayer site decreases first and then increases with the depth,and the maximum acceleration of the tunnel appears at the bottom of the arch;the internal force distribution of the tunnel is affected by the mutual dislocation of the lining joints under the earth?quake,and the internal forces near the arch shoulder and arch foot of the tunnel are obviously concentrated;the deformation degree at the joint is unevenly distributed,and the deformation of the joint near the arch shoulder and arch foot is much larger than that of other parts;the internal force distribution of the bolts is related to the deforma?tion degree of the joint, and the internal force of the connecting bolts at the arch shoulder and arch foot is larger. Therefore, in the seismic design of shield tunnels, it is necessary to increase the design strength of bolts at the arch shoulder and arch foot of the tunnel.
