Study on Non-linear Viscous Elastic-plastic Creep Model of Mica-quartzose Schist

摘要：

Firstly, the creep curves of mica-quartzose schist are obtained through the triaxial creep test, the triaxial creep characteristics are found out by analyzing the creep curves. Secondly, a linear viscoelastic model is established by using model theory, a viscoplastic model is established by using empirical formula, added the above two model, a nonlinear viscous elastic-plastic creep model of micaquartzose schist is obtained. Lastly, the creep model parameters are got by data fitting, the good consistency of the test curves and the theoretical curves show the right and reasonable of the creep model. The non-linear viscous elastic-plastic creep model established can well describe the accelerated creep of mica-quartzose schist.
