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.
