| 摘 要： | 以上海某越江盾构隧道为例,采用二维动力有限元模拟的方法,分析了地震荷载作用下盾构隧道的动力响应,得到了在7度地震作用下,地表土体、隧道周围土体的动剪应力比、动孔压比以及水平方向的加速度.除此之外还得到地震荷载作用下隧道结构、轨道梁的动剪应力,得出了一些具有实际意义的结论,为以后的盾构隧道的设计和施工提供参考.

| Abstract: | Taking a shield tunnel across the Huangpu river as an example,by two-dimension nonlinear dynamic finite element analysis,this paper analyzes the dynamic response of shield tunnel under seismic loading of earthquake intensity of 7.After analyzing the ratio of dynamic shear stress and dynamic pore water pressure,and the horizontal acceleration of the soil on surface of earth and around the tunnel as well as the dynamic shear stress of structure of tunnel and beam of guideway,some conclusions of practical significance are made,which provide references to design and construction of further shield tunnel. |
