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 …

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 instability means that finer particles pass through the constrictions of coarser
particles at a hydraulic gradient well below that of heave or piping, rendering the soil …

To study the mud pumping mechanism in the conventional Chinese ballasted track
subgrade, a physical modelling system which can simulate the cyclic loading-wetting …

Ballast contamination due to intrusion of fine particles from subgrade is characterized as a
conventional source of ballast fouling. To diminish this phenomenon, sub-ballast layer is …

Different layers of soil often have distinct particle sizes. When exposed to the natural
environment, soil is easily affected by natural rainfall, rising groundwater levels, and human …

Existing ballasted track subgrades are prone to complex particle migration problems due to
intermittent train load-rainfall wetting coupling, which causes mud pumping in severe cases …

This study reports on results from a series of geohydraulic, geomechanical, and
mineralogical tests conducted on 12 different landslide samples consisting of broadly …

Mud pumping in rail embankments has been observed in rainy seasons. In this study, a
layered gravel-silt column was tested under cyclic loading to investigate the mud pumping …

The dynamic mechanical response of block-in-matrix-soils (bimsoils) is crucial to the long-
term stability predication of constructions and building structures made of bimsoils. Although …
