FULL-SCALE INVESTIGATIONS OF THE EFFECT OF VERTICAL DRAINS ON THE CONSOLIDATION OF A PEAT DEPOSIT OVERLYING CLAY. DE MELLO VOLUME; A TRIBUTE TO PROFESSOR DR. VICTOR F. B. DE MELLO IN HONOR OF HIS CONTRIBUTION TO THE DEVELOPMENT OF GEOTECHNICAL ENGINEERING IN LATIN AMERICA

Peat covers approximately 20% of the land in Sweden, and in some parts of the country more than 50% of the land area is peat. There is increasing demand for building land and therefore increased interest in the geotechnical characteristics of peat. In this paper, an investigation is described to show how vertical drains can effect the consolidation process in peat. The test field comprised four test areas on marshland near to Chalmers University of Technology, Gothenburg. The site is characterised by very poor subsoil conditions: a top layer of peat 4-5 metres in thickness, underlain by very soft clay. The groundwater level is normally 0.5 metres below the surface. Test areas 1, 3 and 4 were provided with vertical band-shaped drains of the geodrain type, while area 2 was a control. The installation of these drains is described, and consolidation characteristics, settlement, observations, excess pore pressure dissipation, and analysis of results presented.
