Description

Rock mass instabilities represent primary geologic hazards and threaten property and life. In rock engineering, the safety and stability of rock masses is the principal problem. Rock mass can be considered as a kind of discontinuous, anisotropic, inhomogeneous material, where the influence of Earth’s crustal movements, pore fluids, the geothermal gradient, weathering, etc. impart both pervasive and discontinuous joints and fractures to all rock masses. Accidents resulting from rock failure are unacceptable, however analytical tools are still imperfect and fatal instabilities still happen. These facts remind researchers and geotechnical practitioners about the importance of eliminating hazards resulting from rock slope instability. Many natural and manmade steep slopes are prone to instability, and where these slopes comprise fractured rock, effective hazard assessment and mitigation requires reliable tools for rock mass stability assessment.

Earthquakes also have played an important role in the occurrence of landslides, which have caused disastrous consequences. The formation of landslides in the active orogenic belt are generally related to multi-stage tectonic events. For example, the Tibet Plateau is the area with the most severe topographic relief and the most complex geological structure in the world. Beyond acting as a trigger mechanism, seismic waves also contribute to accumulative damage and progressive failure of rock slopes as a fatigue process in the active orogenic belt. In summary, there are many unclear problems in slope stability mechanism and assessment.

The aim of this Special Issue is to bring together original research and review articles discussing innovative research on rock failure and slope instabilities, considering the geological model and the geotechnical, geomechanical, and geophysical characteristics of the rocks to mark the importance of slope instabilities in the field of engineering geology, structural geology, and natural hazards. Submissions showcasing laboratory testing, field investigations, theoretical analysis, and numerical modeling are welcome.

Potential topics include but are not limited to the following:

  • Site investigation for slope instability
  • Rock strength properties and their measurement
  • Crack initiation and propagation mechanisms
  • Ground water flow in fractured rock
  • Damage model and evaluation index for rock mass
  • Geo-hazard associated catastrophic rock failures
  • Numerical modeling of rock damage/fracture
  • Slope stability analyses
  • Earthquake-induced landslides
  • Evaluation models of accumulative seismic damage to slopes
  • Earthquake impact for tailings dam failures
  • Risk assessment of slope instability

Papers are published upon acceptance.
