The earliest relation describing the risk of backward erosion piping, from Bligh in 1915, calculates an overall gradient over the dike. This gradient should be lower than a certain value depending on the material of the dike foundation for the dike to be safe. Later developments rationalize this number, showing the influence of grain size,...

Backward erosion piping is an important failure mechanism for water-retaining structures, a phenomenon that results in the formation of shallow pipes at the interface of a sandy or silty foundation and a cohesive cover layer. Although the pipe depth reveals a lot of information on the backward erosion process, it has never been measured...

The reliability of river embankments is essential for flood risk management. The Po River, which flows through the North of Italy, is safeguarded over half of its length by major river embankments. Performance assessment of such water-retaining structures has become a major concern following some significant flood events in the past. Among the...

Reducing the hydrodynamic drag of marine vessels is a key approach to decrease energy consumption. In addition to saving fuel costs, this also decreases greenhouse gas emissions. One possible method to reduce turbulent drag for a ship is coating its hull with riblets. Riblets are micro-fabricated structures whose design is based on shark skin....

Van Eekelen et al., 2012a, Van Eekelen et al., 2012b and Van Eekelen et al., 2013) have introduced an analytical model for the design of the geosynthetic reinforcement (GR) in a piled embankment. This paper further validates this model with measurements from seven full-scale tests and four series of scaled model experiments. Most of these...

Most analytical models for the design of piled embankments or load transfer platforms with geosynthetic reinforcement (GR) include two calculation steps. Step 1 calculates the arching behaviour in the fill and step 2 the load-deflection behaviour of the GR. A calculation method for step 2 based on the results of model tests has been published by...

This thesis describes the complete redesign of the serious game TeamUp. Introduction At the faculty of Technology, Policy and Management a first concept of a serious game had been developed to assist in teamwork training. The goal of this graduation project was to take this concept and develop it into a full featured prototype that can be used...

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...

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...

In the Netherlands, several field measurements were carried out in piled embankments with a geosynthetic basal reinforcement (GR). This paper presents a series of nineteen 3D model experiments on piled embankments. Purpose of the tests was to find an explanation why the calculated GR strains exceed the GR strains measured in the field. This...

The purpose of this research is to validate a mathematical model for flow through saturated and unsaturated porous media using a bench-scale centrifuge for an accurate determination of the hydraulic conductivity (function of the saturation degree of a soil) within a limited time at a reasonable price. The aim of this paper is to show preliminary...

This thesis reports on experimental research on compensation grouting in sand. It is investigated in model tests, how the shape of the grout bodies made during injection depends on the grout properties, the density of the sand and the way the tubes are installed. The shape of the grout body affects the necessary injection pressure and whether...

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...

In 1997 for the first time construction of bored tunnels in the Netherlands soft soil was undertaken. Before that date essentially only immersed tunnels and cut-and-cover tunnels were constructed in the Netherlands. The first two bored tunnels were Pilot Projects, the 2nd Heinenoord tunnel and the Botlek Rail tunnel. Since then a series of other...

Er wordt een eenvoudige methode gegeven om vanuit de groutinjectieverdeling en de grouteigenschappen, de verticale groutdrukgradiënt direct achter de TBM te kwantificeren. Deze groutdrukgradiënt is nodig als input voor de berekening van het krachtenspel in de tunnelbuis tijdens tunnelbouw. Het bestaande gefaseerde analytische liggerwerkingsmodel...
