In this paper, a triaxial apparatus system was set up. The creep behavior of hydrate-bearing sediments was measured by loading different shear stress on various porosity sediments. The creep curves were attempted to simulate. The experimental results indicated that, the internal cementation of the sediments was changed with the change of porosity. The viscoplastic structural was also changed with the change of porosity. High porosity sediments have a high viscosity and hardness. Moreover, the high porosity sediments have larger initial strain than the low porosity sediments.
