Analytical solution for estimating the stand-up time of the rock mass surrounding tunnel

[Display omitted] •An analytical solution to predict stand-up time of the rock mass was developed.•The solution was based on the rheological deformation model and Abel’s creep kernel.•Allowable displacement of the tunnel wall was also used in calculation.•The results of examples showed the same tren...
