Effect of Pseudo-Seismic Loadings on Probabilistic Slope Stability
Publication: Geo-Risk 2023
ABSTRACT
This paper investigates the reliability of infinite and two-dimensional slopes in cohesive-frictional soils subjected to pseudo-seismic loadings by the random field approach. For the infinite slope, the focus is on the “worst-case” slope angle, with which the probability of slope failure reaches a maximum. And for the two-dimensional slope, the emphasis is on the “worst-case” spatial correlation length, which results in the maximum probability of slope failure. It is shown that the worst-case slope angle is related to the horizontal seismic coefficient and a nondimensional parameter. The worst-case spatial correlation length is most obvious when the deterministic factor of safety is relatively low and the coefficient of variation of shear strength is relatively high.
