Time-dependent failure characteristics of natural jointed granite of deep tunnel under different dip angles conditions
To investigate the time-dependent characteristics of jointed rock masses, a series of single-step true triaxial creep tests were conducted on natural jointed granite samples under different dip angles conditio...

Influence of excavation stress paths on failure feature of deep hard rocks
The fracture of the surrounding rock in deep hard rock engineering is influenced by the stress path during excavation. Taking the stress path as the only variable, a true triaxial experimental system was used ...

Failure characteristics and development mechanism of fault rockburst in a deep TBM tunnel: a case study
An intense fault rockburst recently occurred in a deep tunnel excavated by tunnel boring machine in China, which was taken as a case to study the failure characteristics in detail. The temporal and spatial evo...

Modelling three-dimensional stress-dependent failure of hard rocks
Hard rocks exhibit three-dimensional (3D) stress-dependent failure under true triaxial compression. The deformability and strength of hard rocks under true triaxial compression differ from those under traditio...

Generalized crack damage stress thresholds of hard rocks under true triaxial compression
The rock failure process can be characterized by several distinct stress thresholds: the crack closure stress σcc, crack initiation stress σci, crack damage stress σcd and peak stress σp. Seventy-one true triaxia...
