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 ...

Creep Characteristics of Sands
Soils and Foundations, 1984 ABSTRACT This study is concerned with the creep characteristics of sands under constant principal stress differences of various stress levels which were experimentally obtained by drained triaxial compression tests. In these tests, in order to obtain the creep behavior which is due only to the principal stress difference, but excluding the effect of ...
