Abstract
An experimental apparatus for planar interfacial shear of a hydrate-bearing sediment includes a planar interfacial shear box, a torsional and axial loading device, a nitrogen gas source, a methane gas source, a pressure-volume controller, a water bath device, a back pressure valve, a gas-water separator, a gas flowmeter, and a data acquisition system. The planar interfacial shear box includes an upper pressing plate, an upper adapter, an upper thermal insulation plate, a ram adapter, a lower ram, an upper base, a lower base, a lower thermal insulation plate, a lower adapter, and a lower pressing plate that are coaxially connected in sequence from top to bottom. The experimental apparatus offers a simple specimen preparation method, enabling in-situ formation of a hydrate-bearing sediment in the shear box. The experimental apparatus ensures uniform stress distribution during shearing, and can acquire the interfacial shear mechanical characteristic between the hydrate-bearing sediment and a structure.
