【摘要】 结合雅泸高速公路某双连拱隧道,采用FLAC3D软件,从土—结构相互作用模型出发,运用数值分析方法对该隧道洞口段进行了三维弹塑性分析,并对结果分别从位移、速度、加速度、隧道衬砌内力等方面进行了研究,得到洞口段动力响应的一般规律,并提出相应的建议。更多还原

【Abstract】 By combining with some double multi-arch tunnel along Ya-Lu expressway,the paper adopts FLAC3D software,has the three-dimension elastic-plastic analysis of the cave section of the tunnel by adopting the numerical analysis method from the soil-structure model,researches the result from the displacement,the speed,acceleration and the tunnel lining internal stress,concludes the general law for the dynamic response for the cave section,and points out respective suggestions.更多还原
