WebThe Janbu factor of safety is where the force plot intersects the y-axis (1.269 for the critical slip surface; Figure 8). These methods are available in SLOPE/W; however, the newer methods provided in SLOPE/W (e.g., Morgenstern and Price, Spencer methods) are more rigorous as they satisfy both force and moment equilibrium.
