N2 - The seismic stability of an earth slope reinforced with a row of anchors is analyzed within the framework of pseudo-static approach. First, the upper-bound approach of limit analysis combined with strength reduction technique is employed to solve the safety factor and the corresponding critical log-spiral failure mechanism for a given slope. Then, the slope reinforced with a row of anchors is considered and the analytical expressions for calculating the safety factor are derived. The reasonability of solutions is fully verified by comparison with the known solutions from different methods. Further, a pseudo-static seismic load is applied to the anchored slope, and the new analytical formula is also built. Finally, the parametric study is carried out to illustrate the effect of anchor orientation, anchor position, and seismic loading on slope stability.
