Limit equilibrium slicing methods have been widely used for assessing the stability of natural and man-made slopes. Many methods have been developed so far. They involve various assumptions with respect to the inter-slice forces which lead to different results. In order to get rid of these inconsistencies, attempts is made to incorporate the commonly used slicing methods into a generalized frame work. However, what is the most reasonable result is still unknown. Therefore, a generalized frame work is proposed to find a reasonable bound of solutions of slicing methods for both the two-dimensional and three-dimensional cases. By analyzing the influences of various conditions on the results of stability analysis, the existence and uniqueness of the safety factor are discussed* Analytic formulas of the safety coefficient under different conditions are established. In addition, variation formulas of the safety coefficient are obtained for determining a proper bound of the safety factor. |
