Abstract The geo-mechanical model test has been one of the most widely used methods in rock mechanical research. With the increasing of the buried depth of underground facilities，the deformation and failure behaviours of the deep rock mass exhibit strong time effects. The simulation of the time-dependent rock behaviour has been an important problem without been fully investigated. The time-dependent problems in geo-mechanical model test are divided into several groups；based on the similarity theory，the time similarity relationships of time-dependent processes，including kinematics/dynamics problem，wave propagation problem，creep deformation(based on element models or empirical equations) and long term rock failure problem are deduced. The derived results indicate that the widely used relationship for time similarity is only suitable for the elastoplastic problems in which only kinematics or dynamics process is involved. For other more complicated problems，the time similarity relationship should be determined with the analysis model. The problem of how to simulate the initial strain state of deep rock mass and the long-term aspect of rock failure are also discussed. The time similarity relationships presented provide a valuable reference for geo-mechanical model test on deep rock mass.
