A nonlinear creep model for surrounding rocks of tunnels based on kinetic energy theorem
Journal of Rock Mechanics and Geotechnical Engineering, 2023 The initiating condition for the accelerated creep of rocks has caused difficulty in analyzing the whole creep process. Moreover, the existing Nishihara model has evident shortcomings in describing the accelerated creep characteristics of the ...
