By studying the mechanical characteristics of sandstone, particularly its acoustic emission
(AE) behaviour and fracture morphology, we can obtain insights into its deformation, stress …

Rationale: Over-nutrition will lead to overexpression of PRMT1 but protein hypomethylation
is observed in the liver of obese subjects. The dynamic alteration of the expression and …

The rock mass can be unstable due to the coupling effect of stress and seepage field,
adversely affected by the geological field conditions. In this regard, this study implemented a …

The damage of rock joints or fractures upon shear includes the surface damage occurring at
the contact asperities and the damage beneath the shear surface within the host rock. The …

In the construction of underground geological engineering, a variety of rocks were often
encountered, and the engineering surrounding rocks was prone to shear fracturing. Shear …

The distinction between the shear behavior of tensile-and shear-induced fractures is critical
to understanding the deformation and failure of geologic discontinuities at different scales …

The energy budget and the interplay between stable friction evolution and dynamic stick‐
slips are tested here under continuous slip along rough faults. We conducted 34 direct …

Roughness is an essential factor affecting the shear process of discontinuous surfaces, and
the evolution of roughness is closely related to the mechanical behavior of discontinuous …

Generally, direct shear apparatus is used to determine the shear strength parameters of soil
and rock for designing a geotechnical engineering structure. However, the size of the …

The failure probability and strength of jointed and fractured rock mass under water pressure
action place important constraints on the safety and stability of rock mass engineering. In this …
