Investigating the Mechanical Behavior of Pore-Filling Type Methane Hydrate Bearing Sediments by the Discrete Element Method

Jiang, Mingjing / Liu, Jun / He, Jie

Abstract This study presents a numerical investigation into the mechanical behavior of pore-filling type methane hydrate bearing sediments (MHBS) using the discrete element method. Based on the available experimental data of methane hydrate (MH) samples, MH is modeled as strong bonded clusters. A series of drained triaxial compression tests are simulated and the results show that for the pore-filling type MHBS with MH saturation from 5% to 20%, a higher MH saturation induces a slightly higher shear strength and slightly larger dilatancy. The inclination of the critical state line on the q − p′ plane increases when MH saturation increases. In addition, the evolution rule of deviator fabrics of the strong contact is similar to that of stress ratio q/p′-axial strain.
