Abstract
Spatial variability of soil properties is one of the major uncertainties in geotechnical properties that significantly affect slope reliability and risk. To account for the effect of three-dimensional (3-D) spatial variability, an efficient random finite element method (RFEM), named auxiliary RFEM (ARFEM), is proposed for 3-D slope reliability analysis and risk assessment. The ARFEM consists of two steps: the preliminary analysis using a relatively coarse 3-D finite-element model and subset simulation, and the target analysis using a detailed 3-D finite-element model and response conditioning method. Compared with direct Monte Carlo simulation-based RFEM, ARFEM can provide consistent reliability and risk estimates with much less computational efforts. In addition, it is found that both the horizontal and vertical spatial variability have significant, but different, impacts on 3-D slope reliability, risk and failure mechanisms.
