A micro-bond contact model[1–2] proposed and verified by Jiang[3–5] et al. is incorporated into PFC2D developed by Itasca. Then biaxial test is carried out to simulate the mechanical properties of deep-sea energy soil; and comparison analysis with the triaxial test done by Masui [6] et al. is done. The results show that the macromechanical properties of deep-sea energy soil and the influence of gas hydrate can be reflected through the micro-bond contact proposed by Jiang [1
2] et al.; and the existence of gas hydrate has some contribution to the strength of deep-sea energy soil.
