AbstractNumerical modeling is processed by using of the software ABQUAS to analyze the displacement's distribution and evolution of the pipes and surrounding seabed after dissociation of NGH. It is shown that dissociation scale, thickness of over-layer, elastic parameters of seabed before and after dissociation of NGH have crucial impacts on the deformation of pipes and seabed. In practical engineering design, the dissociation scale and the strength of seabed after dissociation of NGH should be controlled strictly to guarantee the safety of pipes and seabed.
