摘　　要：针对不同层数和软弱土层处于不同位置的分层土质边坡工程,采用FLAC3D有限差分数值计算软件,以安全系数和边坡位移等值线图为边坡稳定性的评价指标,运用强度折减法模拟分析不同坡角对每种分层土质边坡稳定性的影响。在分析每种分层土质边坡不同坡角下稳定性的基础上,得出安全系数的变化规律,进而细彳匕边坡达到临界稳定的坡角范围,并在此范围内分析边坡稳定性。According to different layers and location of soft-soil layer in layered soil slope engineering, using the FLAC3D finite difference numerical computation software, taking the factor of safety and displacement contours as evaluation of slope stability, using strength reduction technique to simulate and analyze the effect of slope angle on each layered soil slope stability. Based on each slope stability in different slope angles, change law of factor of safety is obtained, then refine slope angle range when slope reach critical stability to analyze slope stability within this detailed range.
