- •
Triaxial strength experiments were conducted on hydrate-bearing marine sediments of South China Sea.
- •
Strength property of hydrate-bearing marine sediment was found to be similar to hydrate-bearing kaolin clay.
- •
Hydrate between sediment particles enhances the cohesion of sediment.
- •
Cohesion reduction accompanying with hydrate dissociation greatly affects the failure strength of hydrate-bearing sediment.
