Abstract: The stability of a high cut slope under three difference construction sequences was evaluated by using the commercial software GeoStudio. The deformation and stability effect in the different cut slope angles are analyzed so that the optimized slope angle and slope stability improvement can be obtained. The results indicated that, slope failure could occur for all three different slope angles. The pre-stressed ground anchor can be used for the slope stability remediation. The analysis results also indicated that the minimum earthwork could be obtained when a cut slope angle of 1：1.3 was used. The deformation of all three slope angles could be reduced after the prestressed ground anchors were applied. The surficial red clay soil layer contributed the major deformation of the cut slope.
