Methods for Slope Stability Analysis Baker, 1980 [ 1] suggested a slip circle for determining the factor of safety using the Spencer method and used the dynamic programming. WebJanbu. Janbu is a general method of slices developed on the basis of limit equilibrium. It requires satisfying equilibrium of forces and moments acting on individual blocks (only moment equilibrium at last uppermost block is not satisfied). The blocks are created by dividing the soil above the slip surface by dividing planes.
