摘要	Dissociation of natural gas hydrate in seabed can product amounts of gas. If the soil layer over NGH layer is permeable gas will escape. Gas escape can on one hand lead to the damage of seabed on the other hand lead to the decrease of the density of sea water and so threatens the structures nearby. In this paper movement and expansion behavior of gas in water was first studied then the damage of seabed due to gas escape was studied. Effects of gas pressure thickness of soil layer were investigated. The expansion angle of gas in the water was obtained. The characteristics of the hole size induced by gas escape with gas pressure and soil thickness were also obtained. These results can be as references of deeper research and practice.
