Gradation design method for rockfill materials based on fractal theory
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

Particle breakage characteristics of rockfill materials and correction of Wan-Guo hardening rule
The particle breakage problem of super-high rockfill dams is a hot issue in the current researches. For the rockfill materials of the world's highest concrete faced rockfill dam, Shuibuya Dam, the consolidated drained tri-axial tests with the maximum ...

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 ...

The influence of membranes on tests of coarse-grained materials at low cell pressures
In triaxial tests on small specimens of sands/silts and clays, cell pressures are usually greater than 100 kPa and membranes are relatively thin (~0.3 mm).

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 ...

Several ultra-high earth and rockfill dams up to 250 to 300 m in height are to be built in the intensive earthquake regions of West China. The strong outburst and high uncertainty of strong earthquakes pose a great threat to the safety of ultra-high ...

Dependence of shape on particle size for a crushed rock railway ballast [PDF]
Laboratory testing of railway ballast poses practical difficulties because the particle size is often too large for most standard apparatus. There are therefore advantages in developing a scaled material whose behavior is representative of the full size ...
