International - Special 18th ICSMGE


Admiraal, B.J. (2013): Magic on a square foot. Geotechniek 2013, Special ICSMGE 2013, p14.

In The Hague the famous museum Mauritshuis is undergoing an extension of “only” 10 x 15 m2. The

collection of the museum consists of masterpaintings from mainly The Golden Age of the Netherlands in the 17th century, originally collected by the former stadthouder Prince William V of

Oranje Naussau. The location of the building is in the centre of The Hague next to the houses of

parliament and the office (‘The Little Tower’) of the prime-minister. So any disturbance of this

historic environment should be avoided, like noise, vibrations, traffic collisions, etc.

Geotechnical the situation can be described as fine sands except for a thin peat layer at minus 16 m. All buildings have foundation slabs and thus have no pile-foundations. Like in most places in the Netherlands groundwater level is nearly the surface level.

Brok, C.A.J.M., Detert, O. (2013): Geosynthetic Reinforced Earth (GRE) used as bridge abutment and soil pressure relief. Geotechniek 2013, Special ICSMGE 2013, p18.

The measures taken on the A73/A74 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.

Eekelen, S.J.M. van, Bezuijen, A. (2013): A new equilibrium model for arching in basal reinforced piled embankments. Geotechniek 2013, Special ICSMGE 2013, p9.

Several analytical models are available for describing arching in basal reinforced piled embankments. Between them are limit state equilibrium models. Two of them are frequently applied in Europe. One of them is the model of Zaeske (2001). The other model is the model of Hewlett and Randolph (1988). This paper considers these two models along with a new model: the Concentric Arches Model

(Van Eekelen et al. 2013b). This model is an extension of the first two models.

The paper gives a graphical presentation of the three models and validates them

with numerical calculations and field measurements.

Koelewijn, A.R., Vries, G. de, Lottum, H. van (2013): Full-scale field validation of innovative dike monitoring systems. Geotechniek 2013, Special ICSMGE 2013, p6.

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 analysed in some detail. All tests were done to validate monitoring systems and dike safety information systems. Several systems performed well.

Reijnen, R., Drijkoningen, G. (2013): Seismic ground prediction system on a tunnel boring machine. Geotechniek 2013, Special ICSMGE 2013, p16.

The Dutch company MI-Partners and the Technical University of Delft are two partners in the European Consortium NeTTUN. This consortium consisting of 21 partners has the goal to significantly improve tunnel boring. MI-Partners and the TU Delft will develop a system that generates a map of the soil in front of the boring head.

Using this map the tunnel boring process can be made more robust and safer.

Vollmert, L., Psiorz, C. (2013): Stabilisation of unbound granular layers - reinforcement required? Geotechniek 2013, Special ICSMGE 2013, p21.

The behaviour of unbound base courses is improved by the use of geogrids. The latest results

from large-scale testing carried out by e.g. Cuelho & Perkins (2009) show the effects of different

geogrid products as well as performance-related tests by e.g. Christopher et al. (2008). Some

products provide characteristics for an ideal support of a ductile behaviour of unbound granular layers and reduced rutting.

Zwieten, G.A. van (2013): Some special techniques used in the North-South Line. Geotechniek 2013, Special ICSMGE 2013, p12.

Because of accessibility of the Amsterdam City Center, the city counsel decided for building a

metro-line from the North to the South of Amsterdam.

The line gets 8 stations and has a length of 9,7 kilometers. It is expected the North-South line is

ready for use in 2017, and it will approximately transportate 200.000 travelers a day.

VSF performed on the route of the line some special technics.
