چکیده انگلیسی
A random finite element analysis (RFEA) is employed to study the effect of shear strength spatial variability on the stability of undrained engineered slopes. Based on the RFEA simulation results for 34 (idealized) real engineered slope cases, it is concluded that the coefficient of variation in the spatially variable shear strength and the ratio (vertical scale of fluctuation)/(length of failure curve) have a major effect on the stability reliability. The RFEA simulation results are further used to derive simplified equations for the reliability analysis and the reliability-based design of undrained engineered slopes.
