Abstract Tunnel deformation on the basis of rheological theory is discussed，followed by an exponential fitting of the field monitoring data. Three rheological parameters are then given. Using these three parameters，the appropriate supporting time of second lining is proposed according to the national specifications. Further more，the time of secondary lining in tunnels with different primary lining thicknesses as well as different excavation spans are given using these parameters.
