Vertical joints have significant effects on the stability of shallow-buried loess tunnel. Due to
the presence of vertical joints distributed widely in loess, the formation mechanisms of …

The soil mass above the tunnel generally yields due to the tunnel volume loss. Depending
on the amount of the volume loss, soil unit weight, overburden height and internal friction …

Shield tunneling and post-tunneling steady seepage are accompanied by stress and
displacement variations, which could induce and influence the soil arching effect. Although …

Underground structures/machines may undergo upward and downward movements due to
construction activities or environmental changes. The ground state could be significantly …

High-filled cut-and-cover tunnels (HFCCTs) are common in northwestern China because
their construction allows usable land over the CCT to be reclaimed. However, due to the …

For the project of pipe jacking in cohesionless soil, it is key to determine the vertical load on
jacked pipe so as to predict the jacking force accurately. In this paper, a new parabolic soil …

Owing to lack of consideration of the effects of soil particle flow and sand-cutter friction in
mechanized tunneling in sandy ground, the traditional methods for considering the arching …

Since the ground reaction curve (GRC) is a useful tool for evaluating the formation
deformation and the load acting on an underground structure, it is critical to determine the …

The soil arching effect and properties of the flow field have been recognised as key factors
for controlling soil erosion behaviour at the opening of underground facilities. However, little …

Constructing a new buried structure nearby an existing one or constructing multiple buried
structures in close proximity may change overburden stresses, induce ground movement …
