Effect of fines on shear strength of methane hydrate bearing sand

摘要

Recently there has been much research into Methane Hydrate as adevelopable material in the deep seabed in Nankai Trough. In this study,specimens were prepared to simulate the sediments in Nankai Trough,and a series of triaxial tests were performed on samples with varyingdensity and fines content. From the results of Methane Hydrate bearingsand however, an increase in fines content tended to lead to an increasein stiffness and maximum axial deviator stress, with positive dilativebehavior occurring during shearing.
