Abstract: Abstract The seismic response of tunnels under undrained loading with excess pore pressures accumulation is poorly understood. Two-dimensional dynamic numerical analyses are conducted to assess the seismic response of deep circular tunnels located far from… read more here.

DOI: 10.1139/cgj-2023-0670
Abstract: An important drawback of the hypoplastic model is the inaccurate prediction of the sand behavior under undrained monotonic loading conditions. The model is not able to reproduce the limited liquefaction type response widely observed in… read more here.
