Abstract

Soil slope stability analysis, is one of the most important issues in the design of earth dams, roads, canals and levee. One of these methods is the limit equilibrium analysis with horizontal and vertical slices method.To evaluate the results of horizontal and vertical slice method in the calculation of stability safety factor, at first Two formulations of each method selected, then stability Safety factor has been achieved with the use of these methods for several slopes. The exact amount of stability safety factor by using of the analytical method has been obtained then the accuracy of the each method and comparison of their results with each other is studied.Considering studies at this research, concludes that at generally vertical slices method results exact and with a few confidence rand. Whereas horizontal slices method results have a relationship with selected formulation. In cases where the soil is layered horizontal or issues with horizontal forces, horizontal slices method provide greater ease of use. Finally, explained recommendations for using slice method.
