Developing a mathematical framework in preliminary designing of detention rockfill dams for flood peak reduction

Engineering Applications of Computational Fluid Mechanics, 2019
Hydraulic designing of rockfill detention dam is based on the treatment of nondarcian and non-linear turbulence flow in coarse porous media. Previous literature focused only on the regular outlet ponds, and there is a shortcoming in the design ...

Delayed crushing time for particles of rockfill materials

Yantu gongcheng xuebao
The delayed crushing of rockfill particles is specifically referring to the crushing of particles after loading for a certain period time, which is the basis for the rheological deformation calculation using the discrete element method (DEM).

Modification of scale effects of constitutive model parameters using super large-scale triaxial tests and in-situ monitoring data

Yantu gongcheng xuebao
The significant discrepancy between the calculated deformation values based on the traditional large-scale triaxial test results on rockfill materials (with the maximum particle size of 60 mm) and the monitoring data from the prototype dam raises ...

Strength and deformation characteristics of rockfill materials

Geotecnia, 1979
In the last years, some authors have found to set up rheological models for rockfill materials. This article analyses the most important literature on the subject some suggestions based on laboratorial tests performed in LNEC are made. Three questions are particularly stressed: the study of deformability based on  considerations about the ...

Study on overtopping-induced breach mechanisms of concrete-face rockfill dams

Yantu gongcheng xuebao
Overtopping failure of concrete-face rockfill dams involves a complex water-soil-structure coupling mechanism. Through flume model experiments and based on the theories and methods of water-sand dynamics, soil mechanics, and material mechanics, this ...
