| 摘 要： | 以某交叠隧道为背景,通过有限元分析理论与数值计算方法建立三维模型,研究了双向列车通过时其振动对隧道结构的影响。分析表明：拱底中央受列车振动荷载影响最大,结构满足安全性要求;土压静载仍为结构设计的控制因素。

| Abstract: | Regarding some overlap tunnel as background,3D model was established by the theory of FEM and a numerical method.The effects on lining structure due to the trains moving in opposite direction induced vibration which acts on the overlap tunnels are studied.The analysis shows that,the arch bottom was affected most by the vibration loads of train,and the structure could meet the requirement of safety.Besides,the static soil pressure is the key load for the tunnel structure design. |
