In actual rock engineering, fissures play an important role in determining the mechanical
parameters of rock mass, whereas it is very difficult to construct fissures in cylindrical …

The propagation and coalescence of rock cracks is the direct cause of instability in many
geotechnical engineering structures. To predict the rock crack propagation trajectory and …

Crack propagation can gradually reduce the strength of the rock and eventually result in rock
failure. Coupling effect of stress and seepage in fracture could accelerate the rock failure …
