Dissociation of gas hydrate may cause the strength decrease in hydrate-bearing sediments and result in seabed sinking,slumping and destruction of marine structure foundation.To study this project,first,selecting silty sand from South China Sea as the skeletons,using biological anaerobic fermentation techniques,hydrate-bearing sediments were synthesized.Then centrifuge experimental simulation was conducted to investigate the seabed responses during and after the dissociation of gas hydrate.Characteristics of...
