Study on Nonlinear Viscoelasto-plastic Creep Model of Deep Soft Rock

  Based on the mechanical behaviors of deep soft rock at the accelerating creep stage,a nonlinear rheological cell containing exponential equation replaces classic linear cell,a new nonlinear viscoelasto-plastic creep model of deep soft rock is established on the basis of Nishihara model,and the model can describe the three stages of rock nonlinear creep.Using the least squares method of Matlab to investigate test results,the result shows the new nonlinear creep model accords better with the creep test curves,and verify correctness of the new model.
