Evaluation of input geological parameters and tunnel strain for strain-softening rock mass based on GSI
Abstract 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 classification in one fitting equation....
