Triaxial Compressive Property of Artificial CO2-hydrate-bearing Sediment Sample

The experimental methods of drained triaxial compression test for artificial CO2-hydrate-bearing sediment sample is given and its triaxial compressive property is discussed. The applicability of a constitutive equation which was proposed for CH4-hydrate-bearing sediment sample is discussed. The constitutive equation can almost express the relationship between deviator stress and axial strain of CO2-hydrate-bearing sediment sample.
