Abstract Understanding earthquake nucleation is vital for predicting and mitigating seismic events, saving lives, and enhancing construction practices in earthquake-prone areas. Cascade triggering and preslip triggering are prevalent theories, posing

Understanding different seismic signals recorded in active volcanic regions allows geoscientists to derive insight into the processes that generate them. A key type is known as Low Frequency or Long Period (LP) event, generally understood to be gener

Abstract This study presents an example illustrating the role of in situ 3D stress path method in simulating the roof damage development observed in the Mine-by tunnel at Underground Research Laboratory (URL) located in Manitoba, Canada. The 3D stres

SUMMARY Numerical simulation of non-linear elastic wave propagation in rocks is indispensable for understanding stress/damage dependence of wave velocity changes and the associated micromechanisms. A numerical microstructural model is presented here
Discrete-element-method (DEM) codes were developed in the field of rock mechanics. Compared to continuum codes, it has many advantages such as allowing larger grain displacements, detachment of grains, and simulation of discrete fractures. However, t

Investigations on the Posiva Olkiluoto spalling experiment (POSE) at the nuclear waste disposal site in Olkiluoto, western Finland, have revealed that the presence of anisotropic veined gneiss (VGN) could affect the evaluation of spalling/damage stre

Underground excavation causes rock damage, affecting its stability and fluid transport properties. Traditional experiments usually use loading regime (compressive tests) to damage the sample. However, they cannot mimic realistic in situ conditions wh

A careful comparison of rock behaviour at different scales is essential to determine if laboratory experiments can be useful for understanding the field scale. This research aims to investigate the scaling effect on rock behaviour by comparing P-wave

Fracture network engineering (FNE) involves the design, analysis, modeling, and monitoring of infield activities aimed at enhancing or minimizing rock mass disturbance. FNE relies specifically on advanced techniques to model fractured rock masses and
