英文摘要	Submarine landslide can destroy various engineering facilities. So, submarine slope stability evaluation is not only an important link of the construction safety guarantee and soil mechanics in the new field of ocean direction, but also the development of energy demand. Based on the finite element software Abaqus, the strength reduction method has been introduced to submarine slope stability evaluation. With the same finite element model, the safety factors of the land slope and submarine slope are respectively 1.82, 1.83, and 1.205, 1.215, using two criterions such as run-through of plastic zone and run-through of the equivalent plastic strain zone. The studies show that the submarine slide has the following characteristics: the displacement is 5~10 times larger than that of landslide; the obvious " uplift " and " collapse " phenomenon appears near the slope toe and the top of slope; the slide region is much more wider, deeper, less clearly slip shear zone boundary. © (2013) Trans Tech Publications, Switzerland.
