State-dependent 3D multi-mechanism bounding surface model for rockfills
The rockfill materials have been widely used in the construction of rockfill dams due to their high strength, small deformation and strong permeability. The strength and deformation characteristics of the rockfill materials are essential prerequisites to ...

Experimental study on effect of scaling on compact density of coarse-grained soils
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 ...

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 ...
