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 …

The damage accumulation and strength deterioration within rock masses due to frequent
disturbance loads is a significant concern in the fields of rock mass engineering and deep …

The high-pressure gas combined with the action of the stress wave has a significant effect to
drive fractures and enhance fragmentation in CO 2 blasting. Modelling the whole process …

During opening construction, the accumulated wall displacement and the developing
excavation damaged zone are the results of stress redistribution and inelastic behavior …

Natural defects such as joints, pores, and cracks in rocks seriously threaten the stability of
rock blasting engineering. At present, how parallel joints direct and suppress blasting cracks …

Abstract Design of pressurized tunnels in rock masses which have a time-dependent
behavior is a challenging task. On the one hand, time-dependent behavior not only imposes …

The stability of deep soft rock tunnels under seepage conditions is of particular concern.
Aiming at thoroughly discussing seepage actions and their consequences on the support …

Drill and blast tunneling is a cyclic construction process in which the rock away from the
blast hole is subjected to cyclic blast load that can influence the dynamic behaviour, energy …

Tunneling using the drilling and blasting method induces a blasting damaged zone around
the tunnel, which affects the tunnel stability as well as the resulting support design. In this …

The water-bearing surrounding rock in cold region tunnels is significantly affected by freeze-
thaw (FT) cycles generated by seasonal temperature changes, which can severely lead to …
