SS - Gas Hydrate: Study for the Estimation of Seabed Stratum Deformation in Methane Hydrate Production

摘要

The simulations and numerical analyses of triaxial compression tests on soil samples recovered from the East Nankai trough have been performed by the elasto-viscoplastic constitutive equation. And the numerical analyses of the laboratory model tests on ground deformation in methane hydrate production were carried out by finite element method. From the comparison with the experimental results it is proved that the simulations can express well the behavior of experiments and the numerical analysis results can well reproduce the deformation behavior of ground in the model tests.
