%X In this paper,based on the reological theory of rock,and the principle of seepage,considering the effect of the pore pressure and porosity on deformation of rock,analytical solutions are obtained by using the the Laplace transform (corresponding principle).In certain conditions,the creep curve under pore pressure is obtained by using the principle of effective stress (the equation of effective stress of Terzaghi) and H-K model as the constitutive equation.Comparing this curve with that without pore pressure,we can see that our results agree better with the actual situation.
