Evaluation of input geological parameters and tunnel strain for strain-softening rock mass based on GSI

Scientific Reports, 2022
The regression analysis method is being widely adopted to analyse the tunnel strain, most of which ignore the strain-softening effect of the rock mass and fail to consider the influence of support pressure, initial stress state, and rock mass strength ...

Validation of critical strain technique for assessing stability of coal mine intersections and its potential for development of roof control plans

, 2018
Both room-and-pillar and longwall mining systems develop underground excavations whose stability must be ensured over their entire service life. Even though rock bolts have been extensively used as a support element in US coal mines for about 40 years ...
