| 摘 要： | 隧道上浮问题是盾构水域下浅覆土掘进时所面临的一个重要课题。本文针对某过江隧道江中浅埋段的工程地质条件,建立了隧道上浮计算模型,对江中浅埋段的隧道稳定性进行了数值模拟计算,研究分析了隧道承受上浮力后江底变形及隧道内力的变化情况,得出了一定的规律,以期为后期隧道施工提供参考。

| Abstract: | The problem of tunnel rising is a main topic when tunneling in shallow depth under the water.The calculating model of tunnel rising is established and the stability of the tunnel is analyzed when a certain shallow covering geological condition of a subaqueous tunnel is considered.The changing conditions of the river bottom's deformation and the tunnel's internal force after the rising force is operated on the tunnel are studied.Some rules can be obtained from the study and are expected to supply reference for the construction of the tunnel in the near future. |
