Abstract EN
There are many uncertainties with respect to the assessment of slope stability, and those associated with soil properties should be given particular attention.
The uncertainty theory provides an alternative to treat these uncertainties using parochial cognitive sources.
A novel methodology is proposed to evaluate the stability of slopes based on an uncertain set.
The soil properties involved in the deterministic methods, i.e., shear strength parameters and unit weight, are expressed as uncertain sets, and their membership functions can be assumed to be triangular or trapezoidal for a homogeneous or two-layered slope, respectively.
The parameter values of membership functions are designed according to the means and variations of the soil properties, and then the expected safety factor can be calculated through the operational laws.
Two numerical examples including a homogeneous slope and a two-layered slope illustrate the suitability of the proposed methodology.
The relationship between the variation in the safety factor and the changes in the soil properties is investigated; moreover, the determination of the parameter values of membership is also discussed.
