Abstract: In recent years, the traffic construction of our country grows vigorously. Especially, As the development of the western region in China, The construction of the highway gradually turned to the west. Because of The special terrain condition ,it will inevitably appear high fill embankment. Especially in the area along the river zone, V-shaped gully is everywhere. It is very important that slope instability of high fill embankment with V-shaped gully is bound to affect the normal operation of the highway. Therefore, it is necessary to strengthen research for the stability of high fill embankment with V-shaped gully. The deformation and stress of both linear gravity retaining wall and vaulted gravity retaining wall were analyzed systematically through numerical calculation method in this paper. The results showed that values of the deformation and stress of linear gravity retaining wall were that of radius increased to infinity for vaulted gravity retaining wall, and the values of vaulted gravity retaining wall were smaller than linear gravity retaining wall. This means that vaulted gravity retaining wall was more safe and reliable than linear gravity retaining wall.
