Deformation of rockfill in bodies of rockfill dams
Stroitel 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

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

Journal 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 ...

The Spatial Gradation Characteristics and Intensity Evolution Law of Mine Dump
Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Most of the mine dumps have very prominent slope stability problems. In this paper, by analyzing the gradation characteristics and spatial distribution characteristics of the discharged particles, the functional relationship between the characteristic particle size parameters and the relative height of the dump was obtained.

Aquaculture Research, Volume 2026, Issue 1, 2026.Mark‐recapture studies using fluorochrome dyes are a valuable approach for validating the age determination of fish, yet the optimal chemical marker and its dosage for adult European flounder (Platichthys flesus Linnaeus, 1758) remain unclear. We assessed the effectiveness of tetracycline hydrochloride and calcein at different concentrations for ...
