摘要
桥隧相连是公路和铁路常见的一种结构形式,但其力学特征不甚清楚。文章采取数值模拟,对不同基础形式、不同级别围岩、不同仰坡坡度下桥隧过渡段振动响应进行了仿真分析,为该类型结构形式的设计和施工及车辆运营提供了基础参考。
Transition between bridge and tunnel is a normal type of connection .But its dynamic character is not clear.With Numerical method,and to different types of foundations,different rockmass,different client angles,the dynamic character transition between bridge and tunnel is simulated in this paper.The research re, suits will provide some useful reference for design,construction and operation for this structure.
