The evaluation of engineering rock mass quality is fundamental work for the engineering
activities of rock mass. The increasing scale of rock mass engineering necessitates higher …

Shear slip of rock joints under dynamic disturbance is a major factor causing disasters such
as landslides and cavern instability. To explore the dynamic shear deformation behaviors of …

To explore the mechanical characteristics and failure mechanisms of rock shear fracture
under dynamic disturbance, the laboratory shear test and numerical simulation based on …

To study the shear performance of rock joints reinforced by NPR (negative Poisson's ratio)
bolts, direct shear experiments with different shear rates were carried out on both quasi-NPR …

Natural faults are often heterogeneous with spatially variable cohesion caused by healing
processes. Using rock bridges as laboratory analogs, we investigate how cohesion‐healed …

Supercritical carbon dioxide (ScCO2) fracturing to transform geothermal reservoirs is a new
technology in geothermal development, with great prospects. In this paper, the current …

The research aims to investigate shear fracture behaviors and failure precursors of jointed
rocks under the joint action of normal static loads and dynamic disturbances. To this end …

The spatial–temporal evolution law of shear damage on the joint surface is closely related to
its morphological characteristics. Understanding the heterogeneous failure behavior of the …

A conceptual model of intermittent joints is introduced to the cyclic shear test in the
laboratory to explore the effects of loading parameters on its shear behavior under cyclic …

Understanding fault dynamics is essential for comprehending the underlying mechanisms of
seismic events. This study introduces a novel fault activation-shearing-sliding model within a …
