单拱四车道公路隧道地震响应
|
摘要
针对隧道结构往往受不同方向的地震激励,但地震激励方向很难事先确定,其最大危害方向也难以确定等问题,以天津波为激励地震波,在水平向、竖向和斜向45?激励下,计算大断面隧道的底面、顶面、墙脚和边墙的位移、速度、加速度和应力的分布情况。研究结果表明:在斜向45?激励条件下,单拱四车道公路隧道在地震波作用下,水平方向最大位移、速度、加速度响应值分别为0.25mm,1.84mm/s和15.4mm/s2,竖向最大位移、速度、加速度响应值分别为3.39mm,13.75mm/s和99mm/s2,比同烈度下其他方向的地震响应值大得多。该结果可为大断面隧道抗震设计提供参考。
Based on the fact that collapse of tunnel lining structure and surrounding rock is often caused by earthquake wave in different directions,and the maximum failure degree is unknown in the unspecified directions,and taking the Tianjian wave as earthquake wave,the dynamic response of large cross section tunnels were investigated,where the directions of earthquake wave were horizontal,vertical and inclined at 45°respectively.The displacement,velocity,acceleration and stress in lining structure were presented at the key locations of arch top,lateral wall,wall corner and arch bottom.The results show that the horizontal displacement,horizontal velocity and horizontal acceleration for the direction 45°earthquake wave are 0.25 mm,1.84 mm/s and 15.4 mm/s2,respectively,and that vertical displacement,vertical velocity and vertical acceleration for the direction 45°earthquake wave are 3.39 mm,13.75 mm/s and 99 mm/s2,respectively.The results are greater than those of the other wave directions.The work is helpful for design and construction of single arch tunnel with four lanes in earthquake zones.
