The study of particle migration in porous media under cyclic loading is the key to understand
the mechanism of mud pumping hazard in railway embankments. This paper presents a …

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 …

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 …

The rail network plays an essential role in transport infrastructure worldwide. A ballasted
track is commonly used for several reasons, including economic considerations, load …

Internal erosion may affect soil hydraulic properties, inducing localized deterioration and
even failure of hydraulic geo-structures. Soil is always subjected to stress in engineering …

This paper investigates soil fluidisation at the microscale using the discrete element method
(DEM) in combination with the lattice Boltzmann method (LBM). Numerical simulations were …

Internal instability is the soil's inability to retain fine particles that can be washed away by the
action of seepage flow. Internally unstable soils threaten the safety of infrastructure …

For internally unstable soil, fine particles might migrate in the pore channels of its coarse
matrix because of seepage flow, and fluctuations in the hydraulic gradient might promote …

The effect of fines content on the performance of the wicking geotextile is not clear. This
study developed a simple moisture reduction test method to quantify the effectiveness of the …

The internal structure of sandy cobbles strata is sensitive to disturbances in the urban
underground environment, but the structural evolution process under coupling hydraulic and …
