Abstract: According to the characteristic of the spreading crack under the condition of rheological rock, the authors establish a non-linear viscoelasticoplastic rheological model on the basis of presented models. The model can reflect three stages of the rheological deformation, namely, initial creep, steady creep and acceleration creep. Combing the shear rheological experiment result of the water transfer tunnel at Jingping Ⅱ Hydroplant, the authors compile a arithmetic program of DFP(davidonfletcherpowell) and identify the parameters of rheological model. Accordingly, the result validates that the nonlinear visco-elastic-plastic rheological model is right.
