Abstract: To study the influence of Quhe embankment cross-river bridge pile foundation project on the embankment stability, the FEM was applied to analyze the reinforcement plan of the embankment slope and the construction process. By generalizing the embankment cross-section diagram of the Quhe bridge, a two-dimensional plane strain FEM calculation model was built. The strength reduction FEM method was employed to analyze the circumstances of the designed slope broadening and pile-hole construction. The calculation results showed that the minimum stability safety factor reached 1.179 and met the specification required value 1.150 when the slope gradient was adjusted to 1.00∶3.00. The slope stability safety factor were all larger than 1.150 during the pile hole excavation and the slope stability could be guaranteed, while the seepage deformation and plastic deformation safety problems of pile hole wall existed and protective measures should be taken.

Key words: earth dam seepage, strength reduction method, slope stability, earth-rock dams, pile foundation
