Analytical and Numerical Anti-Floating Study Concerning the Shield Tunnel across the River
In the present paper, we consider the floating problem of river-crossing shield tunnel in the process of construction. Firstly, based on the theoretical analysis of equilibrium states of excavation face and shield segments away from shield tail, we obtain the equation for calculating the minimum thickness of overlying soil in the associated equilibrium states. Secondly, the above derived formula are applied in the Fuhe bridge project, which is a sub-project of No.1 Nanchang metro; at the same time, numerical simulation is carried out to further evaluate the safety with the change of overlying soil thickness. Lastly, some useful conclusions are drawn through comparative study, which is helpful to similar projects.
