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 …

Large displacements controlled by the motion of layered rock strata usually pose a high
hazard to the stability of high sidewalls of the underground caverns in bedded rock mass …

Seepage plays a significant role affecting the tunnel face failure process. However, its effect
on the stability of the underwater tunnel face remains unclear. To study the seepage effect …

The rock fracture characteristics and principal stress directions are crucial for prevention of
geological disasters. In this study, we carried out biaxial compression tests on cubic granite …

High-frequency components in acoustic emission (AE) or seismic radiation attract much
attention as they are directly related to the fracture process. One of the main issues in our …

Tunnels are unavoidably constructed in layered rock masses, and tunnel collapses are often
associated with such layering. Two violent collapses at the Yangshan tunnel were analysed …

Understanding the spatiotemporal evolution of overburden deformation during coal mining
is still a challenge in engineering practice due to the limitation of monitoring techniques …

A discontinuous smoothed particle hydrodynamics (DSPH) method considering block
contacts is originally developed to model the cracking, frictional slip and large deformation in …

To investigate the dynamic mechanical properties and failure characteristics of the
surrounding rock mass in layered strata, composite specimens with a circular hole and a …

Layered rocks (LR) are composed of intact rock matrix (IRM) and various oriented rough
weakness planes (eg, fractures, bedding planes, and foliations). New microcracks can also …
