Seepage-induced fine-particle migration that leads to a change in the conductivity of a soil
matrix is referred to as internal instability. This could jeopardize the structural integrity of the …

Behaviour of granular soils subjected to internal erosion involves complex coupling between
solid–fluid interaction, skeleton deformation and microstructural evolutions. This paper …

This study investigates the evolution of suffusion and mechanical behaviors of gap-graded
soils under anisotropic stress conditions. The interactions between granular assembly and …

The shear behaviors of granular mixtures are studied using the discrete element method.
These granular materials contain real gravel-shaped coarse particles and spherical fine …

This paper reports on a series of laboratory hydraulic tests on a select range of granular
soils compacted at relative densities between 0% and 100%. The critical hydraulic gradient …

Gap-graded granular mixtures, consisting of two different sizes with a great range gap, are
widely used as filling materials in subgrade engineering. The mixtures usually bear vibration …

It is believed that the relative density (D r) can affect the internal stability of the gap-graded
soils and hence the erosion of their fine particles (ie susceptibility to suffusion). This paper …

The flow of small particles in porous media is of interest in many branches of science. In
geotechnical engineering, this phenomenon usually occurs in graded granular materials …

Internal erosion by suffusion within a sand–clay mixture may occur as detachment of clay
particles, which is induced by a decrease in ionic concentration (IC) along with application of …

The heterogeneous transmission of particle stress within the finer fraction has a critical effect
on the development of suffusion\suffosion in gap-graded soils, while quantitative evaluations …
