Granular open filter in rubble mound sand retaining structures: Physical model tests of a negative geometrically open filter layer

For the use of open filters in land reclamations new guidelines are needed as no research is currently done for the configuration of a sand layer is placed on top of a filter layer. This research focuses purely on the interaction between cyclic motions and the described sand-filter layer. A numerical OpenFOAM model is used to extract the order...

Geometrically Open Inverted Granular Filters

This study investigates the use of an open filter in a land reclamation structure. The possibility of replacing the geotextile that secures the core-backfill interface with a granular filter has been investigated. This is easier to install and therefore a potential cost-saving. Experiments have been done to determine the influence of various...

Inversed Open Granular Filters in Land Reclamation Structures: Modeling of the Interface Stability

This thesis is the third study of a research line that focuses on the interface stability of a rubble mound sand retaining structure. The type of interface considered is a geometrically open granular filter because of its economical and constructional benefits. The stability of an open filter structure in which the base layer is located on top...
