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.
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).
