The Inversion Analysis and Material Parameter Optimization of a High Earth-Rockfill Dam during Construction Periods

open access: yes, 2022
Inversion analysis is usually an efficient solution to process the monitoring data of earth-rockfill dams. However, it is still difficult to obtain calculation results that are consistent with monitoring data due to different construction statuses.

Generalized method for assessment of compressibility of rockfill material

open access: yes, 1997
Examination of experimental data of the modelled rockfill materials using parallel gradation technique has revealed that the plots of logarithm of strain at failure against logarithm of confining pressure are linear.

Effect of loading history on time dependent deformation of rockfill

open access: yes, 2012
The paper explores the time-dependent compressibility of coarse crushed quartzitic slate, focusing on the effects of the previous loading history. Large diameter oedometer tests were performed at different relative humidity (or total suctions) and ...

Scale effect of rockfill materials using super-large triaxial tests

open access: yesYantu gongcheng xuebao, 2019
A super-large triaxial apparatus and a common large triaxial apparatus are used to conduct triaxial tests on quarried rockfill materials with the maximum particle size dmax of 200 and 60 mm in parallel gradation. The study mainly focuses on the effect of

Filling standards and gradation optimization of rockfill materials

open access: yesYantu gongcheng xuebao, 2018
Based on the fractal theory, a large number of relative density tests, compression tests and triaxial tests on rockfill are carried out. The relationships among gradation, dry density, compressive modulus, failure strength and particle breakage of ...

A State-Dependent Constitutive Model for Unsaturated Rockfill Materials

open access: yes, 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.

Grouted rockfill a material between rockfill and concrete

open access: yesGeotecnia, 1985
Define-se enrocamento argamassado e compara-se a sua composição, características e processo de execução com outros materiais afins, tais como o simples enrocamento, o betão injectado, o betão cilindrado, o betão ciclópico, o seixo-cimento, o solo-cimento e o macadame.

Constitutive Modelling of Wetting Deformation of Rockfill Materials

open access: yesInternational 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.
