| 英文摘要 | Based on remolded clay sediment obtained from a certain area in the South China Sea, a series of tri-axial unconsolidated untrained compression tests on clay sediment containing tetrahydrofuran hydrate were performed under the conditions of different hydrate saturation and confining pressure. The stress-strain curve of clay sediment containing hydrate consists of three stages: elastic (when strain is less than 1.5%), plastic (when strain is between 2% and 6%) and strain hardening (when strain is greater than 6%) stage, and very different from that of clay sediment which behaves only plastic failure. Moreover, the undrained shear strength of clay sediment containing hydrate increases about 1~7 times than that of clay sediment and decreases by 50% after hydrate dissociation.
