Geotechnics

Bridges, quay walls, dikes, tunnels, they must be sustainable, economical and safe. This requires an appropriate investigation of the subsoil. The Geotechnics Division (GEO) has the task of investigating the nature and characteristics of the soil and to predict its behaviour. Geotechnical tests and measurements are carried out in the field and in the laboratory to investigate nature, stratification and characteristics of the soil. Our division invests in innovative technologies such as advanced testing and online monitoring.

Partners

GEO is one of the 3 partners of the Database of the subsoil of Flanders (DOV). This project valorizes the geotechnical, geological, geothermal, hydrological and pedological data in Flanders. The data collected on the soil in Flanders are made available free of charge. DOV opts for an open data policy and operates in accordance with Flemish decrees and international agreements.

Tunnel in Aalst

In the autumn of 2015 the construction works for the tunnel in the Siesegemlaan will start. The tunnel is to be built under the intersection of the Gentsesteenweg and de Siesegemlaan for  transit traffic. GEO was involved in the geotechnical investigation and the choice of the construction method for the tunnel. During the construction works several parameters will be monitored, such as deformations and strains in the diaphragm wall and the waterlevel in the vicinity of the tunnel.

Deurganckdoksluis: bouw van de grootste sluis ter wereld

De bouw van de Deurganckdoksluis is één van de grootste werven momenteel lopende in België.
De belangrijkste geotechnische aspecten horende bij zowel het ontwerp als de uitvoering van deze sluis worden kort toegelicht.
In dit artikel wordt de nadruk gelegd op het intensieve monitoringsprogramma dat momenteel aan de gang is.
Specifieke aandacht wordt besteed aan de meetapparatuur die werd geplaatst ter begroting van de zwel van de Boomse klei.

Drawing up of a geotechnical dossier for the stabilization of historical quay walls along the river Scheldt in Antwerp

Within the context of the Scheldt Quays Masterplan, the stabilization of the dilapidated historical quay walls was put to study.
For drawing up the geotechnical dossier all available geological and geotechnical information along the quay wall section was collected; beneficial use could be made of the Regional Database of the subsoil of Flanders (DOV). Based on this inventarisation an extensive program of in situ tests and complementary monitoring and laboratory tests was elaborated.

Geotechnical monitoring of a trial pit excavation toward the Boom clay in Antwerp (Belgium)

Abstract. In order to relieve the busy traffic arteries of Antwerp (Belgium), the closing of the ring around Antwerp was put to study by BAM (Beheersmaatschappij Antwerpen Mobiel). The design of this construction requires detailed insight in the behaviour of the overconsolidated Boom clay layer during and after dewatering and removal of the covering soil layers. For this purpose a fully monitored excavation test was performed in order to assess soil behaviour and specific techniques to be used in anticipated projects in the Antwerp area.
