Internal erosion is a complex phenomenon which represents one of the main risks to the
safety of earthen hydraulic structures such as embankment dams, dikes or levees. Its …

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 …

Instability of subgrade soil sometimes associated with soil fluidisation can lead to
uncontrollable deformation and failure at a critical number of loading cycles for a given cyclic …

The instability of railway tracks including mud pumping, ballast degradation, and differential
settlement on weak subgrade soils occurs due to cyclic stress from heavy haul trains …

Internal erosion refers to the movement of fine particles within soil framework due to
subsurface water seepage. Existing criteria for assessing internal erosion usually are based …

Internal erosion can induce significant changes in the mechanical properties of soils, posing
various hazards to dam and dike structures. Despite its importance, our current …

This paper outlines an experimental investigation into seepage-induced failures in soils
subjected to static and cyclic loading. Internally stable, marginal and unstable soils are …

Railways are often subjected to periodic cyclic loading and intermittent rest periods.
Excessive consolidation settlements can affect the performance of railway tracks built on the …

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 …
