摘要： 运用有限差分软件FLAC3D对一段人工堆山加筋边坡进行了分层加载过程的数值模拟和分析，得到了该加筋边坡的抗滑安全系数随加筋密度和格栅铺设长度的变化规律，以及坡体水平位移、土工格栅的受力情况等分布规律，并对计算结果进行了讨论和分析。

Abstract: Staged construction of a reinforced soil slope (RSS) was modelled with  FLAC3D， a finite difference software. The results were used to obtain the relationship between factor of safety of the RSS against sliding and reinforcement length/spacing, along with the discussion on lateral displacement of RSS and distribution of tensile stress along the reinforcement.
