摘要：
Combining seepage finite element calculation and slope stability analysis of strength reduction finite element method, slope stability of earth-rockfill dam is analyzed. When considering the effect of seepage, the seepage field of the dam is calculated by finite element method at first; and then the position of the spill point and the saturation line at steady seepage are calculated through iteration; the seepage forces are calculated according to the hydraulic gradient. Seepage forces, dead weight, buoyancy and seismic force are loaded on the dam; the critical instability state and safety factor of the dam are calculated using temperature-driven parameter reduction finite element method. The analysis results show that the method is reasonable and efficient for slope stability analysis of earth-rockfill dam.
