Equivalent density determination method for dam rockfill materials in mechanical tests
Yantu gongcheng xuebao, 2020 Given the size limitation of laboratory test equipment, it is necessary to scale the rockfill in laboratory tests. The mechanical properties of rockfill have scale effect obviously, and how to obtain the mechanical properties of rockfill accurately ...

Gradation design method for rockfill materials based on fractal theory
Yantu gongcheng xuebao, 2017 According to the fractal theory, the fractal distribution formula of gradation for rockfill materials is deduced. The field gradation data of six dams with clay core and five 200 m-high CFRDs are used to verify the relevant achievements. The result shows

A review of empirical dam breach models
River, Volume 5, Issue 3, Page 328-350, August 2026.Abstract Dam breach modelling is central to flood risk assessment, yet the empirical models commonly used for estimating breach parameters display considerable variability and uncertainty. This review evaluates the performance of widely applied empirical dam breach models and identifies those that consistently show lower uncertainty, such as the ...
