Abstract: Based on an assumed vertical pipeline in seabed, which contains sand and gas hydrate sediment, the deformation and stress of pipeline and sediment are numerically simulated with the different area of gas hydrate dissociation by using the business software ABAQUS. The effects of gas hydrate dissociation area and the thickness of overlaying sand sediment on the stability of pipeline are estimated. It is shown that gas hydrate dissociation obviously affects the deformation of pipeline and sediment. With the expansion of dissociation area, the deformation of pipeline and sediment increase obviously, the shear stress and the stress yielding area in sediment increase too. The pipeline is elastic and stable first, and then becomes to bend and finally be whole instability. When the thickness of overlaying sand sediment increases, the deformation of pipeline and surrounding sediment also increase because of the gravity and the sliding force of overlaying sand sediment.
