dc.description.abstractIt is widely observed that existing tunnels deform and deteriorate over time due to various factors. Among them, tunnel lining permeability plays a significant role. In practice, the development of lining cracks and adjustment of drainage system may gradually alter the permeability of tunnel lining and water drainage path around a tunnel with time. Nevertheless, past investigations usually assume unchanged lining permeability during the whole life of a tunnel but fail to take time-dependent aging process into consideration. In this study, a set of hydro-mechanical coupled analyses is conducted to evaluate the effect of time-dependent crack development on the behaviour of a cross passage twin-tunnel section in Dublin Port Tunnel. The numerical results compare the transverse and longitudinal settlement profiles above the twin-tunnel with and without cross passage. The deformational characteristics of tunnel lining subject to the influence of the time-dependent permeability change are also analysed, which brings more insights into the understanding of aging tunnel structures.en
