英文摘要	This study explores the creep behaviors of schist in different water contents and establish the creep model and its constitutive equations. Firstly, the time-dependent deformation regularity of surrounding rock was studied based on the sericite schist tunnel construction in northwest area of Hubei Province of China. Then rock samples were taken and shear creep tests were carried out along the direction of schistosity plane in natural and saturated states. Based on the in-situ and laboratory tests results, a viscoelastic-plastic creep model was constructed through model identification and introducing a nonlinear rheological component. Finally, parameters of the creep model were obtained by multiple regression and back analysis and the rationality of the creep model was verified by comparing with the experimental data.
