| Abstract | In this paper, the stability of base circle slopes is analyzed based on the theory of random fields. The closed-form solution of the safety factor and the failure probability of base circle slopes are obtained using the integration method. The effects of the spatial variation of the mechanical parameters of soils on the stability of base circle slopes are investigated. The mean values of the safety factor and the failure probability of base circle slopes are determined. The effects of spatial correlation length on the failure probability of base circle slopes are studied. The results show that for homogeneous slopes, the accuracy of the vertical integration model is greater than that of the horizontal integration model. For layered slopes, the effectiveness of the horizontal integration method is validated by a Monte Carlo simulation. Therefore, the horizontal integration model is more suitable for the layered slopes than the vertical integration model. © 2017 Springer-Verlag Berlin Heidelberg |
