Other AbstractNatural gas hydrates occur worldwide and have been a hot topic due to its energy and geohazard potential. Gas hydrates-bearing sediments (HBS) are natural soils that contain natural gas hydrate. The mechanical response of HBS is crucial for predicting the stability of sub-marine sediments and the gas production from natural gas hydrate reservoir. In this paper, the mechanical constitutive models and the numerical simulations of HBS are summarized. The Duncan-Chang models are simple but cannot describe the strain softening stage, the critical state models are complex. Currently, the numerical simulations of HBS require a simple and accurate model. The multi-phases coupling numerical simulation can study the influence of various parameters on the mechanical properties of the gas hydrate bearing sediments. The changes in the mechanical properties of sedimentary media during decomposition process need to be studied in depth.
