Brittle failure, also known as rockburst, is a violent phenomenon that occurs during the
excavation of hard rock in areas with high geostress, particularly at great depths. The …

The static and dynamic failure processes of hard rocks were simulated by compression tests
to investigate the precursors of hard rock instability. In the tests, acoustic emission (AE) …

The nonlinear stress and deformation response of tunnel excavation unloading under high
and complicated geostresses are important features of deep rock tunnel engineering, and …

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

In this study, we numerically examine the microcracking behaviors of Alxa porphyritic granite
under direct shear using a novel grain-based model considering particle-scale softening …

An accurate description of the morphology of a joint surface is necessary to interpret its
shear behavior. Accurately distinguishing the shear behavior differences may be difficult if …

It is believed that the loading rate significantly affects the damaging behaviors of layered
rocks. However, previous studies have mainly focused on the inherent bedding structure …

Micromechanical cracking processes in rocks directly control macro mechanical responses
under compressive stresses. Understanding these micro-scale observations has paramount …

The rock mass in nature is in most cases anisotropic, while the existing classifications are
mostly developed with the assumption of isotropic conditions that not always meet the …

Ground deformation caused by mining affects the safety of underground mining and
buildings. High-resolution characterization of ground deformation response to latent sources …
