【摘要】 旁通道与隧道的连接处是隧道抗震的薄弱环节,但目前有关旁通道抗震性能的研究开展得还很少。为此,提出了一种联络通道地震响应分析的动力有限元方法,利用该方法对某盾构隧道工程的旁通道进行了横向及纵向地震响应分析,并分析了不同接头形式对结构抗震性能的影响,得出了有意义的结论。更多还原

【Abstract】 The joints between the connectional passages and the tunnels are weak links in earthquake,whereas little correlative research has been done so far.In this thesis,a seismic response analysis method of connectional passages was presented.Then,this approach was applied to research the transverse and longitudinal seismic response of a connectional passage of a shield tunnel,with emphasis on the influence of the type of joints on the structure’s seismic behavior,and some valuable conclusions were drawn in the end.更多还原
