The influence of normal stress and sliding velocity on the frictional behaviour of calcite at room temperature. Insights from laboratory experiments and microstructural observations [PDF]

, 2016
The presence of calcite in and near faults, as the dominant material, cement, or vein fill, indicates that the mechanical behaviour of carbonate-dominated material likely plays an important role in shallow- and mid-crustal faulting. To better understand

Two cases of post-limit deformation of rock mass surrounding underground opening

IOP Conference Series: Earth and Environmental Science, 2020
Abstract The authors analyze stress state of rock mass around an underground opening in two cases of post-limit plane-strain deformation: when the modulus of compression is much higher than the modulus of post-limit deformation and when the modulus of post-limit deformation is much higher than the modulus of compression.

Fracture distribution and deformation mechanism of surrounding rock in two-way extremely unequal pressure soft rock roadway

Meitan xuebao
The failure of butterfly plastic zone in roadway surrounding rock is an important reason for the large deformation of roadway surrounding rock. In recent years, it has attracted the attention of roadway support workers.

Research on Failure Characteristics and Zoning Control Technology of Thick-Soft Surrounding Rock for Deep Gob-Side Entry Retaining

Shock and Vibration, 2020
Controlling the large deformation caused by bed separation failure of thick and soft surrounding rock in gob-side entry retaining is difficult. The deformation and failure modes of thick and soft surrounding rock are summarized and classified based on ...

Earthquakes: from chemical alteration to mechanical rupture

, 1998
In the standard rebound theory of earthquakes, elastic deformation energy is progressively stored in the crust until a threshold is reached at which it is suddenly released in an earthquake.

Field investigations of high stress soft surrounding rocks and deformation control

Journal of Rock Mechanics and Geotechnical Engineering, 2015
AbstractField investigations of high stress soft rock deformations show that the high stress soft rock roadway can slide with large deformation. Severe extrusion and floor heave can also be subsequently observed. The supported roadway can be locally damaged or completely fail, where the floor has a large deformation and/or is seriously damaged.

Time-dependent deformation analysis of the surrounding rock mass around a tunnel

IOP Conference Series: Earth and Environmental Science, 2020
Abstract A numerical time-dependent model is established by incorporating the stress corrosion model into the three-dimensional discrete element grain-based model (3DEC-GBM) to analyze the fracture evolution and instability mechanism of the surrounding rock mass around a circular tunnel.
