dc.description.abstractTunnel hydraulic deterioration has been widely reported and investigated in many past studies where, nevertheless, the tunnel lining permeability was assumed as constant and the time-dependent hydraulic degradation process was neglected. To investigate the hydraulic ageing behaviour of Dublin Port Tunnel, in this paper, a modified ground-lining relative permeability analytical model was derived and current deteriorated lining permeability was estimated using field monitoring water flow data. Compared with the initial watertight status of Dublin Port Tunnel, the current hydraulic state of the tunnel was found to be partially permeable after more than a decade’s operation. The results from numerical simulations showed that the assumption of a constant hydraulic permeability during the lifetime of tunnel structures may not evaluate the ageing tunnel deformational performance process realistically. It is important to consider the effect of time-dependent hydraulic deterioration process on tunnel performance.en
