AbstractWith an integrated apparatus for hydrate-bearing sediment (HBS) syntheses and tri-axial test, a series of shear tests on the static and dynamic properties of the methane and THF hydrate-bearing sediment consisted with fine silty sand were carried out. The stress-strain and shear strength characteristics were analyzed. The development of the pore pressure and the remaining strength of the HBS and the saturated fine silty sand under cyclic loads after the dissociation of hydrate were investigated. It was shown that the HBS behaved as plastic failure. The larger the confined pressure was, the higher the strength was. After some cycles, the sediment after the dissociation of hydrate could develop to liquefy.
