摘      要：A novel approach based on the upper bound theory is proposed to assess the stability of excavated slopes with spatially variable clay in undrained *** proposed random limit analysis is a combination of the deterministic slope stability limit analysis together with random field theory and Monte Carlo simulation.A series of analyses is conducted to verify the potential application of the proposed method and to investigate the effects of the soil undrained shear strength gradient and the spatial correlation length on slope *** groups of potential sliding surfaces are identified and the occurrence probability of each sort of failure mechanism is quantified for various slope *** proposed method is found to be feasible for evaluating slope *** obtained results are helpful in understanding the slope failure mechanism from a quantitative point of *** paper could provide guidance for slope targeted local reinforcement.
