摘要：
Modern methods for calculating slope stability in current finite-element programs involve the stepwise uniform reduction of the soil strength parameters. However, prediction of the strength-reduction law under the influence of external factors is not actually possible. The suggested method for safety-factor minimization will produce the most reliable estimation of slope stability. This idea is illustrated by calculating the safety factor for embankments composed of clay loam and sand. (C) 2014 American Society of Civil Engineers.
