Numerical simulation of size effect on shear strength and deformation behavior of rockfill materials
Yantu gongcheng xuebao, 2018 The scale effect of rockfill materials is crucial to predicting the strength and deformation of earth-rockfill dams. Due to their large particle size and the experimental restrictions, large triaxial tests on full scale samples are seldom conducted.

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.
