摘要
采用固定边界和粘-弹性边界对隧道结构进行了地震响应分析,得到了隧道结构在两种边界条件下的应力和位移响应以及水平地震荷载作用下衬砌的薄弱部位。结果表明,在隧道结构地震分析的数值模拟问题中,宜采用粘弹性边界模拟地基的无限性。
The tunnel seismic response is numerical simulated with the fixed boundary and the viscous-spring boundary. The stress response,the displacement response and the weak portion of the link are gotten. The results show that the viscous-spring boundary should be adopted to imitate limitless of foundation in the numerical simulation of seismic response analysis of tunnel.
