Study on the breaking process of jointed rock mass by disc cutters based on digital image correlation and infrared thermography [PDF]
E3S Web of Conferences, 2021 Jointed rock masses are frequently encountered during the TBM excavation. To investigate the rock breakage mechanism of jointed rock mass by disc cutter and precursory information before rock failure, a series of indentation tests were performed on shear

Seismic response of rock joints and jointed rock mass [PDF]
, 1996 Long-term stability of emplacement drifts and potential near-field fluid flow resulting from coupled effects are among the concerns for safe disposal of high-level nuclear waste (HLW). A number of factors can induce drift instability or change the near-field flow patterns.

Degradation mechanism of intermittent jointed sandstone under water-rock interaction
Yantu gongcheng xuebao, 2021 Under the action of periodic rising and falling of reservoir water level, the damage and deterioration of the jointed rock mass in the hydro-fluctuation belt of a reservoir bank slope is likely to cause the reservoir bank slope to develop in an unstable ...
