| 摘 要： | 以某越江公路盾构隧道为工程背景,在利用成层反射理论分析场地地震波特性的基础上,采用反应位移法研究了公路盾构隧道的动力响应特性,其中:盾构隧道衬砌结构环向和纵向接头采用弹性铰模拟,天然地层作用在隧道结构上的剪切力和强制位移由成层反射理论动力分析程序DYNEQ获得.研究表明:由剪切力和强制位移引起的地震附加内力规律基本相当...

| Abstract: | Under the precondition of analyzing seismic wave characteristics by taking advantage of layered reflection theory,based on a cross-river highway shield tunnel,the corresponding dynamic properties of highway shield tunnel were studied by using response displacement method.The cylindrical and longitudinal bolts of the lining were simulated by using elastic hinges,and shear force and compulsory displacement of the tunnel structure in natural ground were obtained by dynamic analysis program DYNEQ using layered ... |
