摘要
在对地下隧道进行动力有限元分析时,作者采用无限元模拟土体位移逐渐衰减的规律和边界条件.通过对某矩形双洞口隧道的抗震分析,为地下隧道的抗震设计提供了参考.
In order to simulate the gradual attenuation of displacement in the soil field, the infinite element is adopted to resolve the boundary condition in the analysis the seismic design of subway tunnel. The paper presents the principle of assembling element stiffness matrix in the programming, Finally, the seismic analysis of double hole with rectangle section problem shows the distributing rule of dynamic stress of tunnel, and some advice is advanced for the construction of same structure,
