Overview geotechnical model tests on dike safety at Deltares

Three on-going dike safety studies (on: macro stability, piping and flow slides) in the Netherlands make use of geotechnical physical models. A short outline of these projects is presented; the physical models chosen are described and discussed. The three studies use different physical models, depending on the research questions at the beginning...

Piping in loose sands – the importance of geometrical fixity of grains

Piping is one of the possible failure mechanism for dams and levees with a sandy foundation. Water flowing through the foundation causes the onset of grain transport, due to which shallow pipes are formed at the interface of the sandy layer and an impermeable blanket layer. In the past, the mechanism has been investigated predominantly in...

SBW Hervalidatie piping HP2.2 Medium-schaalproeven (Analyserapport)

Doel van het SBW piping project is het identificeren van onzekerheden binnen de huidige piping toetsingsregels en deze eventueel te verkleinen of elimineren. Het programma is gestart met kleine schaalproeven om invloeden van verschillende zandkarakteristieken te bestuderen. Uit deze proeven volgt de invloed van de verschillende...
