PROBLEM TO BE SOLVED : To provide a method for making a gas hydrate deposit by which the gas hydrate deposit suitably reproducing a state of a gas hydrate present in the ground is made by a simple and inexpensive apparatus, and the gas hydrate deposit suitable for a test piece for a dynamic test can be made; and to provide the apparatus for making the gas hydrate deposit, and the test piece for the dynamic test of the gas hydrate deposit, suitable as the test piece for the dynamic test.
SOLUTION : The method for making the gas hydrate deposit comprises mixing previously made granules or powder of the gas hydrate cooled to a prescribed temperature not higher than the ice point, with granules or powder of earth and sand imitating the ground so as to imitate the interior of the ground to provide a mixture spuriously reproducing the mixed state of the gas hydrate with the earth and sand and the like in the ground, holding the mixture in the stress state and the temperature state resembled to the interior of the ground, and keeping the stress state and the temperature state until the mixture is stabilized. |
