This paper reviews the progress made by our research team in the construction of large
cross-section subsea tunnels using the drilling and blasting method. Our research on the …

Face stability protection is a critical issue during large cross-section tunneling. This study
investigates the evolution mechanism of tunnel face instability with different ground …

Tunnels excavated in soft rock under high in situ stress are usually accompanied by large
time-dependent deformation, slow convergence, and long periods of increased support load …

The mechanical responses of tunnels reinforced by combined bolt–cable system are
investigated in this paper. An analytical model of the convergence-confinement type is …

Deformation and damage of the rock mass induced by excavation operations can result in
the tunnel wall convergence. Accurate prediction of the convergence is crucial for ensuring …

Numerous subway tunnels have been built in soft upper and hard lower composite strata.
However, the stability and bearing capacity of composite strata are difficult to predict …

Large deformation is a crucial factor in deep-buried tunnels constructed through soft rocks
with a high geostress. Taking the deep-buried Baozhen tunnel through layered shale as an …

Large deformation has been a common engineering problem during the construction of
tunnels in areas with high geo-stress, the large deformation of layered surrounding rock …

When an underwater tunnel is constructed using the drill-and-blast method, the rock mass
around the tunnel undergoes significant blasting damage. Quantifying the combined effect of …

Rock load on lining structures increases over time for tunnels buried in rheological rock, and
in addition deterioration of primary lining is common due to its structural characteristics and …
