Abstract: It is essential to consider the uncertainty in soil properties for a realistic assessment of slope stability. The goal of this study is to propose a framework for the reliability assessment of unsaturated slope under rainfall infiltration based on available data and current state of knowledge. The main contributions are: (1)a joint probability model for SWCC is proposed (2)a modified Metropolis-Hastings algorithm is proposed for an efficient simulation-based reliability estimation (3) the effects of the uncertainty in SWCC and hydraulic conductivity in unsaturated seepage and slope stability are studied systematically.
