Abundant oil and gas resources are stored in the continental slope region of northern South China Sea. However, due to the submarine landslide disasters, submarine pipelines and cables and other submarine facilities were damaged, which seriously affected the development of oil and gas resources, leading to a huge economic losses. In order to ensure the safe operation of the submarine gas pipeline, it is necessary to carry out some researches in the submarine slope stability. In this paper, an uncertainty analysis method is applied and a distribution model which is suitable for slope stability influencing factors of this region is put forward. In addition, the risk of submarine slope is analyzed, plotting submarine landslide risk evaluation maps. Different stochastic characteristics of variables such as water depth, angle of slope, shear strength and earthquake acceleration etc can be reflected reasonably, which is helpful for the safety of oil and gas transportation.
