Abstract
An experimental apparatus for studying an interfacial shear characteristic between a hydrate-bearing sediment and a structure includes a triaxial shear pressure cell, a torsional and axial loading device, a methane gas source, an upper computer, a first pressure-volume controller, a water bath device, a second pressure-volume controller, an oil tank, a back pressure valve, a gas-water separator, a gas flowmeter, and a data acquisition system, where the triaxial shear pressure cell includes an upper pressing plate, an upper fixed disc, a loading rod, a pressure chamber upper cover, a high-pressure sealing cover, a lower rotating base disc, a thermal insulation plate, a lower pressing plate, a top cap, and a base. The experimental apparatus can achieve in-situ artificial hydrate formation for the study. The multi-directional load control-based shear method supports interfacial shear experiments under a complex stress path, providing hardware support for studying the interfacial shear mechanical characteristic.
