DOI: 10.1016/j.tust.2018.09.007
Abstract: Abstract Most subways excavated in nonhomogeneous and water-bearing soils but few existing analytical models focus on the combined effect of soil nonhomogeneity and pore water pressures. To address this issue, a three-dimensional (3D) rotational collapse… read more here.
