Experimental study on effect of scaling on compact density of coarse-grained soils
Yantu gongcheng xuebao, 2019 There is a certain difference in compact density of rockfill materials between the real gradation and corresponding scaling gradation. In order to describe the difference quantitatively, the scaling effect can be divided into two parts, changes of the ...

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.
