Analysis methods for slope stability are routinely applied by geotechnical engineers. A realibility approach, using probability calculations which account for the variability in soil strength, is superior to the factor of safety approach. The method is based on the point estimate method and allows engineers to calculate a probability of failure for the slope. Examples show how soil variability affects slope reliability and how the method is applied. The factor of safety is 1.30 in the first two examples. In the first example, the soil deposits are uniform and the probability of failure is acceptable; in the second example, the soils have more soil strength variation and the probability of failure is higher than recommended.
