Major Technologies for Safe Construction of High Earth-Rockfill Dams
Engineering, 2016 The earth-rockfill dam is one of the primary dam types in the selection of high dams to be constructed in Western China, since it is characterized by favorable adaptability of the dam foundation; full utilization of local earth, rock, and building ...

A State-Dependent Constitutive Model for Unsaturated Rockfill Materials
, 2021 This chapter presents a state-dependent elastoplastic constitutive model for both saturated and unsaturated rockfill materials. The model, which is developed within an extended critical-state framework, uses two independent stress state variables: total stress and total suction.

Constitutive Modelling of Wetting Deformation of Rockfill Materials
International Journal of Civil Engineering, 2018 In this paper, the constitutive framework of hypoplasticity is used to model long-term deformations and stress relaxations of weathered and moisture sensitive rockfill materials. The state of weathering of the material is represented by a so-called solid hardness in the sense of a continuum description.

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 ...

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.
