利用有限差分强度折减法，讨论自然状态下的边坡稳定性情况，对锚索框格梁支护结构受力及其对边坡稳定性影响进行分析，并将各开挖步下的边坡稳定性情况进行了对比，计算结果表明：经锚索框格梁加固支护后，边坡稳定性显著提高，锚索对土体起到明显的反向锚固作用，同时，边坡滑动面首次出现在开挖支护面之上，表现为潜在的滑体将越过支护面滑出，为满足边坡的使用功能，需作长远考虑。

Based on finite difference strength reduction method,the analysis of natural slope stability was dis-cussed,and the stress of anchor frame beams supporting structure and their effects on slope stability were ana-lyzed.Meanwhile,the slope stability of each excavation step was estimated comparatively.The results show that the stability is significantly improved after being supported,and cables have an obvious reverse anchoring effect on soil.At the same time,the slope sliding surface firstly appears upon supporting surface of excavation,and po-tential landslides may slide across the support surface.In order to meet the utility of slopes,it would be better to have long-term consideration.
