Abstract

This paper outlines the engineering geological properties of the clayey soils of North Lefkoşa (Nicosia, Cyprus). On the basis of their physical properties and their engineering characteristics, the Miocene, Pliocene and Quaternary deposits were divided into six units: unconsolidated man-made fill, unconsolidated surficial recent alluvium, unconsolidated surficial young alluvium, consolidated old alluvium, highly weathered soft rock units and slightly weathered relatively resistant rock units. Laboratory tests indicated a generally high swelling potential, which would account for the damage seen in many single and two-storey buildings as well as major roads.

Résumé

L’article présente les propriétés géotechniques de sols argileux de la partie nord de Nicosie (Lefkosia) à Chypre. Sur la base de leurs propriétés physiques et de leurs caractéristiques géotechniques, les dépôts miocènes, pliocènes et quaternaires sont répartis en 6 unités : remblais anthropiques sous-consolidés, alluvions très récentes sous-consolidées, alluvions récentes sous-consolidées, alluvions anciennes consolidées, roches tendres fortement altérées, roches de résistance moyenne légèrement altérées. Les essais de laboratoire indiquent généralement un fort potentiel de gonflement, ce qui pourrait expliquer les dommages affectant des habitations d’un ou deux niveaux ainsi que des routes construites sur ces sols argileux.
