Full scale field test pile driveability in Antwerp

ABSTRACT The closing of the ring around Antwerp (Belgium) was put to study by BAM. The construction of two-layer tunnels necessitate
excavations up to great depth. Purpose of this unprecedented (sheet)pile driving test was to assess performance of state of the art top
range (sheet)pile driving equipment, soil resistance and specific techniques to be used in the Antwerp area. A special focus was on the
dense glauconite sands. The retrevievability also had to be put to the test. From the tests it was learned that full length pre-drilling by means

Kanaal Ieper-Leie geschiedenis van de "drogen vaart"

In de periode 1863 - 1913 werden meerdere pogingen ondernomen om een kanaal te graven van Ieper naar de Leie in Vlaanderen. Zoals in
die tijd ook voor de aanleg van spoorwegen gebeurde, werd de aanleg van het kanaal in concessie gegeven, in dit geval aan de Compagnie
du Canal de la Lys à l’Yperlée. Dit houdt in dat de nodige fondsen voor de aanleg van het kanaal werden geleverd door privé investeerders, die
eens het kanaal in gebruik tolgelden of vaarrechten mochten innen.

Conceptual method for rapid diagnosis of the failure behaviour of Flemish dikes

In order to cost-effectively protect the population against floods, the government uses cost-benefit analyses when considering any infrastructure interventions that might be carried out. For this purpose, the costs (for construction and maintenance) and benefits (avoiding damage and casualties) have to be analysed.

Design and implementation of dewatering: Belgian guidelines

When dewatering work is carried out, the roles and responsibilities of the various parties involved are often unclear. A working group, set up in the heart of the TI-KVIV Society ‘Soil Mechanics and Foundation Engineering’, drew up guidelines to assist the client and designer in the design of a dewatering operation, from the soils survey through to the text of the technical specifications. The guidelines also provide assistance to the client, designer and contractor in aspects concerned with the performance of the dewatering operation.

Sands containing glauconite

Glauconite is a clay mineral that occurs in the form of dark green granules in many marine sands. The granules are more or less equal in size to the particles of the sand matrix in which they occur. However, because glauconite consists of clay minerals, it is much softer than the silica sand. Glauconite granules are therefore easy to deform and shatter. This has an important impact on the geotechnical properties and behaviour of sandy soils with a significant level of glauconite.

The regional geotechnical database “DOV'

ABSTRACT : Databank Ondergrond Vlaanderen (DOV) aims to be the overall database compiling and offering subsoil information
of Flanders (Belgium). Actual data consist of drillings, CPT, groundwater wells and groundwater supply licences.
Since the introduction of the website, DOV has proved to be a powerful tool in geotechnical design; data
collection form the basis of preliminary design, global inventory and analysis of geotechnical parameters for

Comparison of monitoring techniques for measuring deformations in an excavation

ABSTRACT: Active monitoring is often suggested as a method to decrease the required safety coefficients in the design stage of a construction. In order to apply active monitoring, precise, reliable and interpretable measurements of the actual behaviour of the structure and soil-structure interaction are required. To obtain this data, accurate and robust monitoring tools should be available at an acceptable cost. An online monitoring test set-up was realized in a railway-infrastructure project site in Anderlecht (Belgium).
