Dynamic probability evaluation of safety levels of earth-rockfill dams using Bayesian approach
Water Science and Engineering, 2009 AbstractIn order to accurately predict and control the aging process of dams, new information should be collected continuously to renew the quantitative evaluation of dam safety levels. Owing to the complex structural characteristics of dams, it is quite difficult to predict the time-varying factors affecting their safety levels.

Numerical analysis of earthquake response of an ultra-high earth-rockfill dam [PDF]
, 2013 Abstract. Failure of high earth dams under earthquake may cause disastrous economic damage and loss of lives. It is necessary to conduct seismic safety assessment, and numerical analysis is an effective way. Solid-fluid interaction has a significant influence on the dynamic responses of geotechnical materials, which should be considered in the seismic ...

Slope Stability Analysis of Earth-Rockfill Dams Using MGA and UST [PDF]
Journal of Computational Engineering, 2015 The nonlinear Unified Strength Theory (UST), which takes into account the effect of intermediate stress and nonlinear behavior on geotechnical strength, is applied in slope stability analysis of earth-rockfill dams (ERD) in this paper. The biggest drawback for general determination of slip surface is that it must presuppose the shape of slip surface ...
