中文摘要：
露天矿靠帮开采设计对边坡的稳定系数比较敏感.现有的边坡剖面通常采用Flac进行边坡二维稳定性计算,Flac3D进行由二维剖面扩展而成的三维边坡稳定性计算.本文以一系列边坡模型为研究对象,分别采用Flac与Flac3D软件进行分析比较.结果表明,仅有剖面的情况下,采用Flac比Flac3D在边坡稳定性的计算中更有优越性.
英文摘要：
The steep end--slope mining design is sensitive to stability factor of the slope. The given slope profile is often analyzed with Flac, and Flac3D with an expanded slope model. In the paper, a series of slopes with different height were analyzed with Flac and Flac3D. The result shows that it is superior using Flac than Flac3D in open--pit slope stability factor analysis when there is only slope profile available.
