In this paper,we established a seismic resistance and damping model to study the effects of tunnel under seismic waves.We took the entrance of Galongla Tunnel as prototype, drafted the similarity relationships of the model.Damping layers and the measuring points of shaking table model have been arranged. We carried out loading test of the shaking table. Compared with the results of finite eleme...

Seismic liquefaction affects badly the safety of underground structures. For dynamic responses tunnel in liquefied watered sandy stratum one rail transit projects Shanghai, this paper proposes a tunnel-foundation shaking table model test and analyses electrolytic desaturation technology on surrounding soil, which provides some theoretical guidance for seismic designs Shanghai projects. The resu...

The tunnels located in the shallow depths of loose saturated sand are significantly prone to liquefaction-induced uplift. Research works are, therefore, progress propose efficient techniques for mitigating In this study, 1 g physical modeling was used assess performance helical piles decreasing effects pile length, number helixes, and spacing plan view were investigated. uplift mechanism tunnel...
