Deep Underground Science and Engineering, EarlyView.A novel analytical method is proposed to evaluate the shear stress effect on the progressive compressive failure and microcrack growth direction in brittle rocks. The shear stress effect on the wing crack growth direction during the progressive compressive failure is determined. The initial crack angle effect on the y‐direction peak stress and the wing

Deep Underground Science and Engineering, EarlyView.A series of water infiltration tests and gas permeability tests were conducted on granite and granite–bentonite samples. According to the results, the interfaces between granite and bentonite and the damaged granite were considered to be the preferentcial pathway for gas migration.

A review of multiscale numerical modeling of rock mechanics and rock engineering
Deep Underground Science and Engineering, EarlyView.Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

Deep Underground Science and Engineering, EarlyView.The Fobinso granitoids are granodiorites, while the Esuajah granitoids are granites based on their mineralogical composition. The granitoids are generally enriched in LILE and LREE than HFSE, MREE, and HREE, indicating mixing with crustal sources during their evolution.
