After the excavation of deep underground engineering, the complex 3D high-stress
redistribution occurs in the surrounding rock, resulting in deterioration of mechanical …

Hydraulic fracture propagation under natural fracture distributions has always been a hot
topic in unconventional reservoir stimulation. In this work, the hydromechanical behavior …

Rock materials contain various scales of pre-existing flaws that greatly influence the stability
of rock engineering. The study of strength and failure behavior of pre-flawed rock enhances …

In this study, we adopt the Discrete Element Method (DEM) to evaluate the influence of
Freeze–Thaw Cycles (FTCs) action on the mechanical properties of rock. To overcome the …

This paper presents a hydro-mechanical phase field model that integrates the unified phase
field fracture theory and Biot's theory, emphasizing the correction of the volumetric strain …

Hydraulic fracturing is a critical technology employed in the exploitation of shale gas and the
enhancement of geothermal resources. It is important but challenge to investigate the …

Hydraulic fracturing and its associated seismic behaviour are increasingly important in the
resource sector. In this paper, hydraulic fracturing and induced seismicity by both the …

The reason for instability in a rock mass with a weak interlayer is not only the sliding failure
of the rock interlayer structural plane but also the tip crack propagation caused by the stress …

Highlights A rock fracture closure analysis considering the transition from elastic deformation
to fully plastic flow is established. The contact analysis incorporating the transition regime is …

The existence of inherent microcracks in granite makes accurately describing crack
propagation and fracture behaviors challenging, which is crucial in engineering …
