It has become an inevitable trend of human development to seek resources from the deep
underground. However, rock encountered in deep underground engineering is usually in an …

The review covers the development and the state of the art in deep-sea mining rock
mechanics, equipment and challenges. It begins by introducing the significance of deep-sea …

Coupled static-dynamic tests were carried out on notched semi-circular bend (NSCB)
granitic specimens using a modified split Hopkinson pressure bar (SHPB) device, to …

Different defects are widely distributed inside natural rock masses, and the development of
these defects poses a potentially severe threat to the entire structural stability and safety …

Strain rockburst poses a great threat to the construction safety of deep engineering,
especially induced by dynamic impact loads such as blasting from the adjacent tunnel …

Many large engineering projects, eg, the Sichuan–Tibet Railway, inevitably cross the
earthquake active areas and the geology complicated zones, facing the challenges of …

Shear slip of rock joints under dynamic disturbance is a major factor causing disasters such
as landslides and cavern instability. To explore the dynamic shear deformation behaviors of …

In underground engineering constructions, fractured rock masses are likely to be subjected
to three-dimensional static stress and dynamic loading simultaneously. In this study, via a …

In underground rock engineering, rock structures at great depth are commonly subjected to
water infusion, static geo-stress as well as the dynamic disturbances. It is thus essential to …

Investigation of rock progressive damage under static confinement and strain rates facilitates
the generation mechanism of natural fault damage zones. A triaxial Hopkinson bar …
