Seismic performance of concrete tunnel–sand–pile interaction by the shake table test

Deep Underground Science and Engineering, EarlyView.
This research presents the square root sum of squares response of displacements and tunnel moments under the Kobe and Loma Prieta seismic excitations with a peak ground acceleration of 0.05 g for various dry relative densities of local sand in Bangladesh.

A comprehensive study on in situ stress field characteristics and changes in rock mechanical properties in deep mines in northeastern Yunnan, China

Deep Underground Science and Engineering, EarlyView.
This paper studies the distribution characteristics of the current in situ stress field in northeast Yunnan Province by using multisource stress data, including in situ stress measurements, focal mechanism solutions, and borehole damage information, and comprehensively determines the in situ stress magnitude and direction in the mining area.

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 ...

Petrogenetic and geochemical characteristics of some auriferous granitoids in the Kumasi Basin, Ghana: Implications for geodynamic settings and controls of orogenic gold mineralization in the Edikan Gold Mine

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.

Study on damage and failure characteristics of loaded gas‐bearing rock–coal–rock combination structures

Deep Underground Science and Engineering, EarlyView.
The influence of gas on the instability and failure of rock–coal–rock combinations is considered. The damage characteristics of gas‐bearing rock–coal–rock combinations under different confining pressures, axial loading rates, and gas are revealed. A constitutive model for gas‐bearing rock–coal–rock damage considering gas is established.
