DOI: 10.1016/j.tust.2018.09.021
Abstract: Abstract Soft soil poses more challenges to the construction of large-diameter shallow-buried tunnels than other soils: the surrounding rock mass is more easily disturbed, and the tunnel stability is more influenced by various factors. This… read more here.
