| Summary: | Hydrate-bearing sediments are characterized as soils in which the pore space is partially or fully occupied by ice-like crystalline solid consisting of hydrogen bonded water lattices encapsulating guest gas molecules, mostly methane in natural environments. These sediments are found along marine continental margins and in permafrost regions. The main focus of this thesis is to investigate the behaviour of hydrate-bearing sediments subject to triaxial compression. The work presented includes (1) an investigation into the formation process dependency of hydrate growth habit, spatial distribution, and saturation (the key deterministic factors of the physical behaviour), (2) a novel formation methodology to isolate the effects of formation habit from those of spatial variation in hydrate distribution, (3) an investigation into the accurate estimation of hydrate saturation, (4) and a comprehensive series of tests to investigate the initial effective confining stress and hydrate saturation dependent stress-strain ... |
