Comparison between Duncan and Chang’s EB Model and the Generalized Plasticity Model in the Analysis of a High Earth-Rockfill Dam

Journal of Applied Mathematics, 2013
Nonlinear elastic model and elastoplastic model are two main kinds of constitutive models of soil, which are widely used in the numerical analyses of soil structure. In this study, Duncan and Chang's EB model and the generalized plasticity model proposed

A particle-breakage critical state model for rockfill material

Science China Technological Sciences, 2015
Particle breakage has a significant influence on the stress-strain and strength behavior of rockfill material. A breakage critical state theory (BCST) was proposed to describe the evolution of particle breakage. The breakage critical state line in the breakage critical state theory was correlated with the breakage factor, which was fundamentally ...

Long-term deformation characteristics of high concrete-faced rockfill dams under cyclic loading of water

Yantu gongcheng xuebao
The long-term deformation of high concrete-faced rockfill dams is one of the key technical problems during their construction. Most studies have attributed the long-term deformation to rockfill creep, but the prototype monitoring data of some high ...

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 ...

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 ...
