Abstract: The static stability of the tailing dam by the influence of environmental factors in various aspects,Capillary water is also one of the important factor,So For the tailings dam Using FLAC2D numerical simulation by the action of capillary water and Regardless of the capillary water.To draw out the two cases of X and Y direction displacement contours,Cloud principal stress changes,Shear stress cloud image edge incremental change.And to calculate the safety factor of the two conditions,Found in considering capillary effect of the static stability of the tailings dam when the water will be reduced,Safety factor is reduced by 35%.The analysis results Provides a scientific basis for The safe operation of the tailings dam.

Key words: capillary water,tailings dam,the static stability,FLAC2D
