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.

BAM test excavation

An extensive test campaign is currently ongoing for the construction of the Oosterweelverbinding in Antwerp. Together with BAM, the company Denys and BBRI, our division is examining the characteristics of the soil to a great depth. Vibration and piling-driving testing have already been completed. The monitoring of a test excavation to 25 metres depth is nearly finished. The results will be reported after a thorough analyses.

Bouw van een Nieuwe Sluis in Terneuzen

De bouw van de Nieuwe Sluis in Terneuzen is een uitdagend project dat wordt uitgevoerd binnen
een nauw samenwerkingsverband tussen Nederland en Vlaanderen. In dit artikel wordt
een overzicht gegeven van het grondonderzoek dat in de voorbereidingsfase werd uitgevoerd.
Tevens worden de belangrijkste geotechnische aspecten en risico’s toegelicht, verbonden aan
de specifieke ondergrond in het projectgebied, met name door de aanwezigheid van Boomse
klei en glauconiethoudend zand.

One-dimensional consolidation of overconsolidated clay using Constant Rate of Strain testing

The main method for the determination of consolidation parameters in Flanders is still the incremental loading test (IL test). This method can take up to several weeks for some typical Flemish overconsolidated (OC) clays. In theory, the same relationship between settlement and vertical stress can be obtained by performing a constant rate of strain test (CRS test).
