Fracturing behaviors of flawed granite induced by dynamic loadings: A study based on DIP and PFC

open access: yesDeep Underground Science and Engineering, EarlyView.
This research examines granite's mechanical properties under split‐Hopkinson pressure bar testing, focusing on factors such as grain size and flaw dimensions. The study reveals that tension cracks are prevalent across grain sizes, with most intergrain cracks occurring between feldspar and quartz.

A comprehensive review of experimental studies on shear behavior of bolted rock joints with varying rock joint and bolt parameters and normal stress

open access: yesDeep Underground Science and Engineering, EarlyView.
This study reviews the research findings on the shear behavior of bolted rock joints in deep underground engineering, where they face high stress, high water pressure, and engineering disturbance. This study examines how the shear strength of bolted rock joints is affected by various factors, such as normal stress, rock compressive strength, joint ...

Damage evolution of surrounding sandstone rock under charging–discharging cyclic loading in the natural gas storage of abandoned mines based on the discrete element method

open access: yesDeep Underground Science and Engineering, EarlyView.
This study established a true triaxial numerical model of rock mass with the discrete element method and explored the crack evolution of surrounding rock of underground roadway gas storage during cyclic loading and unloading and the damage numerical model considering residual deformation.

Digital reconstruction of three‐dimensional contours and its application to microstructural evaluation of postblast rock fissure surfaces

open access: yesDeep Underground Science and Engineering, EarlyView.
In order to study the change rule of the fracture surface morphology after blasting, based on the improved cube covering method and the 3D contour digital reconstruction model, a quantitative microstructure characterization method combining the roughness evaluation index and the 3D fractal dimension is proposed, which is applied and validated in the ...
