The property of time–dependent deformation of rockmass surrounding tunnel is studied and a new method is presented to analyse the the time–dependent convergence displacement of surrounding rockmass of circular opening in this paper. Taking rockmass as a quasi–creep material and using integral creep model, the creep parameters and predisplacement of the rockmass can be estimated by field convergence measurments
