Rock-mass engineering geomechanics is a branch of engineering geology that focuses on the formation and evolution law of engineering rock mass by the theories and methods of geomechanics. It has gradually evolved through engineering practice since 1950s. A rock mass often consists of various types of discontinuous structures such as joints and faults, which has dominant effects on the deformation and failure behaviors of the rock mass under certain environment. Due to the presence of discontinuous structures, it has always been a formidable task to characterize the mechanical behaviors of the rock mass.
In the past few decades, significant progresses have been made in the area of rock-mass engineering geomechanics. The most representative developments involve the rock mass classification and the rock mass failure criterion that consider discontinuous structures, with extensive applications in engineering practice such as tunnels and slope designs.
In recent years, great interests, and new challenges as well, are present in following areas: (1) Deep underground space applications such as hydraulic fracturing for shale gas and oil development, waste disposal, and energy storage; (2) Characterization of the rock mass, such as the coupling effects among thermal, fluid, and mechanical fields on rock-mass mechanical behaviors; and (3) Dynamic mechanical behaviors of the rock mass subjected to the catastrophic earthquake events. Moreover, recent advancements in laboratory instruments have enabled advanced study of geometric and mechanical features of rock mass from multiscale perspective. Examples of innovative experimental approaches include high energy X-ray CT scanning coupled with rock mechanics testing system; dynamic shear apparatus adopted to study dynamic shear properties of rock mass with discontinuities subjected to seismic loads; and remote sensing techniques applied to fractures characterization and stability assessment of open-pit mine slopes.
