摘要

Based on review of current research of time-dependent reliability and analysis of the characteristics of landslide hazards, an idea that the bayes approach can combine natural information and epistemic information to reduce knowledge-based epistemic uncertainties.Thus, the Bayesian approach can serve as a powerful tool for information updating and provides a new solution for time-dependent reliability analysis and for investigating potential landslides. Then a probabilistic analysis using Bayesian approach is applied to spatially evaluate the aging/life of landslides. The application to the assessment and prediction of landslide life result shows that the renewal of information can be capable of capturing the deteriorating characteristics of slopes effectively and make reliability estimate of a landslide more accurate and realistic.
