Slope Stability Analysis by Swedish Slip Circle Method Using C-Programming
Abstract: The side slopes of an earthen dam should be safe against shear failure. Out of the various methods of stabilityanalysis of slopes, “Swedish Slip Circle Method” is commonly used in practice. Here in the Swedish circlemethod, potential failure surface is assumed to be cylindrical in shape (i.e., circular in cross section). Afterdetermining the actuating and resisting forces for assumed failure surface, the factor of safety is calculated. Theslope is considered …
