Reduction in strength and stiffness in rocks attributed to an increase in water content has
been extensively researched on a large variety of rock types over the past decades. Due to …

Under complex geostress caused by long-term geological evolution, approximately parallel
bedding structures are normally created in rocks due to sedimentation or metamorphism …

Layered sedimentary hard rock is an important inducing factor that deforms the tunnel
structure. To explore the aging deformation and mechanical characteristics of damaged …

The failure mechanism and failure mode of anisotropic rock masses are very different from
those of isotropic rock masses. For unsupported tunnels, the failure modes of anisotropic …

The effect of bedding plane orientations on shear strength and failure mechanisms of shale
is investigated, with an emphasis on the shear parameters of the bedding planes. This study …

Shales are considered to be both source and cap rocks, and play an important role in
various geotechnical applications including oil and gas exploration and production. A deep …

Multi-stage fracturing of horizontal wells to recover shale gas has attracted substantial
renewed interest in the physical and mechanical characteristics of shale. The mechanical …

Deep resource extraction is of great importance in advancing shale gas development. To
obtain the fracture behavior of deep anisotropic shale reservoirs under in-situ temperatures …

This paper presents bonded-particle discrete element modeling with embedded smooth
joints for simulating the mechanical behavior of transversely isotropic rock with systematic …

Bedding planes or layers can have a serious effect on the mechanical behaviour of shale
rock. Fractures occurring along bedding planes form a fracture network in shale hydraulic …
