Abstract: The slope stability is simulated and analyzed by finite difference program FLAC software and strength reduction theory.The mining pit slope stability is analyzed by the stress-strain cloud graph,element displacement vectorgraph,plastic state graph,layered destruction yield graph and safety coefficient for a rational assessment of the slope stability.

Key words: Slope stability analysis, Finite difference method, FLAC,Safety coefficient
