Research Abstract |
We have conducted dissociation tests by depressurizing method for sand containing CO2 hydrates, in order to investigate the dissociation behavior of sediments in deep sea bottom at Nankai Trough. Also, we have developed a numerical method of chemo-thermo-mechanically coupled analysis, and simulated the dissociation tests. From the present study, we have confirmed that the proposed numerical method well reproduce the change in temperature, and settlement during the dissociation tests.
