| 摘 要： | 隧道可液化土层围岩对地震动作用非常敏感,可液化土层动孔压的产生和发展使得地下结构受到上浮作用,从而影响地下结构的稳定性.通过对可液化土层中隧道动力响应计算,研究了不同静应力场隧道围岩动孔压场分布、围岩液化区域分布以及衬砌结构仰拱底与拱顶的动孔压差变化.研究结果表明,不同静应力场对围岩可液化土的动孔压分布、液化区域分布及...

| Abstract: | Under the strong seismic loading on tunnels and underground structure in saturated liquefiable soil,the soil is sensitive to vibration,and the dynamic pore water pressure increases,so underground structures move up under the vibrating pore water pressure.Finally,underground structures are destroyed seriously.The dynamic responses of tunnels in saturated liquefiable soil are calculated.The dynamic pore water pressure distribution of the tunnel surrounding,and tunnel foundation are studied.The results show th... |
