Grouting mechanism in fractured rock considering slurry-rock stress coupling effects
Yantu gongcheng xuebao, 2018 The slurry-rock stress coupling effects have a great influence on the grouting process in fractured rock. In order to describe the dynamic grouting process, a piecewise equation is used to govern the deformation process of rock fissure, and a theoretical

Linear elastic fracture mechanics predicts the propagation distance of frictional slip [PDF]
, 2014 When a frictional interface is subject to a localized shear load, it is often (experimentally) observed that local slip events initiate at the stress concentration and propagate over parts of the interface by arresting naturally before reaching the edge.

Simulating spatial and temporal evolution of multiple wing cracks around faults in crystalline basement rocks [PDF]
, 2007 Fault zones are structurally highly spatially heterogeneous and hence extremely complex. Observations of fluid flow through fault zones over several scales show that this structural complexity is reflected in the hydrogeological properties of faults ...

Identifying the real fracture hidden in rock microcrack zone by acoustic emission energy
International Journal of Mining Science and TechnologyIdentifying the real fracture of rock hidden in acoustic emission (AE) source clusters (AE-depicted microcrack zone) remains challenging and crucial. Here we revealed the AE energy (representing dissipated energy) distribution rule in the rock microcrack
