摘要: 将强度折减理论与FLAC软件相结合,利用有限差分程序FLAC软件来模拟分析边坡稳定性。以应力应变云图、单元位移矢量图、塑性状态图、分层破坏屈服面图及安全系数对采场边坡稳定性进行分析,进而合理评价边坡的稳定状态。

关键词: 边坡稳定分析, 有限差分法, FLAC, 安全系数

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
