By using an integrated experimental apparatus for syntheses of hydrate-bearing sediment(HBS) and tri-axial mechanical tests,a series of static tests were conducted on the silty-clay containing tetra-hydro-furan(THF) hydrate.The samples were prepared with the silty-clay obtained from the South China Sea where gas hydrate has been found.The stress-strain curves before and after hydrate dissociation and the strength parameters were obtained.It is shown that the hydrate-bearing silty-clay behaves as elastic-pla...
