摘要: We investigate the uncertainty in bedrock depth and soil hydraulic parameters on stability of a variably-saturated slope Rio de Janeiro, Brazil. couple Monte Carlo simulation three-dimensional flow model with numerical limit analysis to calculate confidence intervals safety factor using 22-day rainfall record. evaluate marginal joint impact uncertainty. The mean its 95% interval evolve rapidly response storm events. Explicit recognition properties increases significantly probability failure.
