Full-scale field validation of innovative dike monitoring systems
A.R. Koelewijn, G. de Vries, H. van Lottum, Geotechniek Special ICSMGE, September 2013, pagina 6
Three large scale field tests on dikes have been carried out at the IJkdijk test site in the Netherlands. Two tests involved piping, micro-instability of the sand core and erosion from overtopping. Both dikes failed on micro-instability. The third test involved slope stability with a deep sliding plane. The failure process of this dike is analyzed in some detail. Volledige artikel
A new equilibrium model for arching in basal reinforced piled embankments
S.J.M. van Eekelen, A. Bezuijen, Geotechniek Special ICSMGE, September 2013, pagina 9
Several analytical models are available for describing arching in basal reinforced embankments. Between them are limit state equilibrium models: Zaeske (2001) and Hewlett and Randolph (1988). This paper considers these two models along with a new model: the Concentric Arches Model (Van Eekelen et al. 2013). This model is an extension of the first two models. Volledige artikel

Summary about the extension and renovations of the Mauritshuis museum in The Hague. The existing two story cellar will be transformed into an underground entrance-hall. Directly adjacent to the cellar a lift shaft will be constructed in the ground. Volledige artikel
Seismic ground prediction system on a tunnel boring machine
R. Reijnen, G. Drijkoningen, Geotechniek Special ICSMGE, September 2013, pagina 16
Dutch company MI-Partners and the Technical University of Delft are developing a system that generates a map of the soil in front of a boring head. Using this map the tunnel boring proces can be made more robust and safer. Volledige artikel
Geosynthetic Reinforced Earth (GRE) used as bridge abutment and soil pressure relief
C.A.J.M. Brok, O. Detert, Geotechniek Special ICSMGE, September 2013, pagina 18
The measures taken on the A73/74 demonstrate convincingly the use of innovative construction methods even with complex civil engineering structures. As a result of positive experiences gained world-wide with the Muralex GRE system, it can be expected that this cost-efficient construction method, which also produces aesthetically pleasing designs, will gain greater acceptance.
