dc.description.abstractNatural gas hydrate, which can form complex vein structures within fine-grained sediments, pose a significant geohazard if the hydrate were to dissociate. Therefore, understanding the role of hydrate veins on the geomechanical behavior of hydrate-bearing fine-grained sediments is essential for sediment stability assessment. This thesis presents the results of a laboratory study conducted to further understand the fine-grained soil behaviour with simplified cylindrical tetrahydrofuran (THF) hydrate veins within the soil. Compression tests were conducted on standalone THF hydrate veins of different diameters to determine their strength and stiffness. Subsequent consolidated undrained (CU) triaxial tests were conducted to determine the behaviour of fine-grained soils containing the same-size hydrate veins. Factors such as vein size and effective stress were considered to develop relationships between vein size and strength/stiffness of the hydrate-bearing soil. The results are used to consider the role that hydrates veins may have on natural sediments formed at different depths.en_US
