| 中文摘要 | Gas hydrate dissociation in marine sediments will cause increase of excess pore pressure, loss of soil particle cementation and breakdown of soil structure, which may result in large deformations of the strata and offshore structure foundations. Based on the permafrost and ocean environmental conditions, a high pressure and low temperature apparatus has been self-designed and a series of triaxial tests have been carried out to study the influence of gas hydrate dissociation on mechanical properties of gas hydrate-bearing sediment. The effects of dissociation time, confining pressure and dissociation temperature on the mechanical characteristics of the sediment containing gas hydrates are investigated. Moreover, the mechanical parameters of cohesion and internal friction angle are quantitatively analyzed during hydrate dissociation. This study is important for understanding of the evolution of sediment mechanical properties during hydrate dissociation, for controlling hydrate reservoir stability and project risk. © 2015 Taylor & Francis Group, London. |
