| 摘 要： | 根据以往的受震破坏经验,在公路隧道的高烈度地震带,地下工程可能会遭受严重震害,尤其洞口段为抗震薄弱区,本文采用FLAC3D软件,从土—结构相互作用模型出发,运用数值分析方法对隧道洞口段进行了三维弹性和弹塑性分析,得出了相应结论,并对结果进行分析,指出隧道抗减震设计中应注意的事项,并提出相应解决措施。

| Abstract: | On the basis of the knowledge highway's ruin of the past,in high earthquake intensity area of highway,underground structure may be fall into ruin for the seismic motion,especially,the entrance of tunnel is the weakest of the tunnel.As based on the soil-structure interaction model,adopting the soft of FLAC3D and numerical analysis method,the tunnel entrance has been computed by the elastic and plastic method,the results obtained are discussed and the measures for design and solution are presented. |
