Suffusion involves fine particles migration within the matrix of coarse fraction under seepage
flow, which usually occurs in the gap‐graded material of dams and levees. Key factors …

Filter layers are extensively employed in dam structures as a mitigation method against
internal erosion, which facilitates the interlocking and clogging of the suffused base soil due …

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 …

Numerous incidents and failures of earth slopes, dykes, levees and embankment dams are
caused by internal erosion. At a time of global climate change, rapid pore-water pressure …

The suffusion mechanism of well graded gravels in the application of high speed railway
roadbed is still not fully understood. Field inspections of high speed railway show that …

Geotextile and granular filters are widely used in civil (eg earth dams, embankments,
drainage trenches, etc.) and environmental (eg landfills, permeable reactive barriers, etc.) …

The ubiquitous phenomenon of particle migration and clogging in porous media, particularly
when involving cohesive fines necessitates a critical need for in-depth understanding from a …
