Gradation design method for rockfill materials based on fractal theory

open access: yesYantu 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

Deformation of rockfill in bodies of rockfill dams

open access: yesStroitel stvo nauka i obrazovanie [Construction Science and Education], 2019
Introduction. The main factor determining the stress-strain state (SSS) of rockfill dam with reinforced concrete faces is deformability of the dam body material, mostly rockfill. However, the deformation properties of rockfill have not been sufficiently studied yet for the time being due to technical complexity of the matter, Materials and methods. To

Rockfill embankment settlement analysis of a concrete faced rockfill dam

open access: yes, 2022
In concrete faced rockfill dam construction (CFRD), after the completion of rockfill embankment, the construction process is given a halt until the major part of the settlement of rockfill embankment is completed and the construction of concrete ...

Modelling of shear strength of rockfills used for the construction of rockfill dams

open access: yesSoils and Foundations, 2018
Abstract This paper presents the results of examination of shear properties of rockfills used for the construction of rockfill dams. Based on the results of a large number of experiments, mathematical model of the shear strength of the rockfill was derived, as a function of normal stress, initial compaction and uniaxial compressive strength of intact

Creep model for rockfill materials based on particle breakage energy consumption

open access: yesYantu gongcheng xuebao
Due to the complex rheological characteristics of rockfill materials, the existing empirical creep models have problems such as unclear meaning and too many parameters.

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 ...

Influence of the Uncertainty in the Dam‐Breach Hydrograph on the Flood Hazard Assessment in a Valley Area

open access: yesJournal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT The reliability of flood event simulations is a crucial aspect in terms of saving lives. The worst flood scenarios derive from possible dam failures. For earthen dams, the breaching mechanism, triggered by overtopping or piping, is affected by several modelling uncertainties, which propagate downstream and may influence flood hazard mapping ...
