Effects of Methane Hydrate Saturation and Confining Pressure on Strain-Rate Dependence of Artificial Methane-Hydrate-Bearing Sediment in Triaxial Compression Test

In this study, drained triaxial compression tests were conducted on artificial methane-hydrate-bearing sediment samples under various conditions of methane hydrate saturation and confining pressure. During the axial loading in the tests, the strain rate was alternated between 2 predetermined rates tha...

Description
Summary:In this study, drained triaxial compression tests were conducted on artificial methane-hydrate-bearing sediment samples under various conditions of methane hydrate saturation and confining pressure. During the axial loading in the tests, the strain rate was alternated between 2 predetermined rates that were recommended in an earlier work. On the basis of the results, we examined the effects of methane hydrate saturation and confining pressure on the strain-rate dependence of triaxial compressive strength.
