ABSTRACT To safely and effectively explore the natural methane hydrate, it is crucial to examine mechanical behavior of hydrate‐bearing sediments (MHBSs). Natural hydrate unevenly distributes in pores or bonds with soil particles MHBS, changing MHBS including stiffness, shear strength, dilatancy. This paper presents an anisotropic critical state model for considering pore‐filling cementing effects. Based on unified both clay sand, equivalent ratio defined address effect. Cohesive strength its hardening law are introduced characterize cementation. describe behavior, inherent anisotropy hydrates modeled separately, rotation stress‐induced anisotropy. Comparisons existing triaxial tests synthetic demonstrate that proposed comprehensively describes MHBS. Detailed predictions indicate affects hydrate‐dependent stiffness dilatancy which become more pronounced increasing saturation. Cementing effect increases initial peak The influence parameters pre‐peak stress–strain relation noted, saturation enhances These contribute a better understanding between morphologies properties.
