摘要: 从滑坡的基本特征、变形特征以及成因等方面分析了怒江下游某段滑坡的独特性,认为刚体极限平衡法与锚索抗滑桩相结合是该滑坡处理的最优方法,通过GeoStudio计算出滑坡的最小安全系数。以安全系数的计算作为依据,用锚索抗滑桩的方法对其进行支护处理,可使得滑坡处于稳定状态。结果表明:此种方法确实取得了很好的效果,对该地区以及类似地区的边坡评价与治理也具有很好的参考价值。

Abstract: The unique nature of the landslide from the basic characteristics,deformation characteristics and formation mechanism of the landslide are analyzed,and it is considered that the combination of limit equilibrium analysis rigid body and anchor cable anti-slide pile is the best choice of the landslide control in the area of downstream of Nu River.A minimum safety factor of landslide is calculated by GeoStudio.With the safety factor as a starting point,the landslide is kept be in a stable state by the support treatment with anchor cable anti-slide pile.The results show that this method really reaches well effect which provides very good reference value for the landslide evaluation and governing of this region as well as other similar areas.
