Abstract
The geotechnical properties of silts have not been investigated extensively, because they are not found in every soil environment. It is even more difficult to understand the behaviour of silts when they are encountered in appreciable volumes. It has recently been claimed that such fine-grained soils have a potential for liquefaction, similar to sands a fact that was confirmed during the 1999 Marmara earthquake in Turkey. This paper provides a basis for explaining the unique behaviour of silts in seismic conditions by investigating their physical and mechanical features. The results are ultimately expected to provide a satisfactory answer to the as yet unexplained issue of how silts behave during earthquakes.
Résumé
Les propriétés géotechniques des limons n’ont pas été complètement étudiées car ces sols ne sont pas très communs. Il est par ailleurs difficile de comprendre le comportement des limons lorsqu’ils se présentent sur de fortes épaisseurs. Récemment, il a été affirmé que de tels sols fins ont un potentiel de liquéfaction semblable à celui des sables, un fait confirmé en 1999, lors du séisme de Marmara en Turquie. L’article, étudiant les caractéristiques physiques et mécaniques des limons, est un document de base pour expliquer leur comportement particulier sous sollicitations sismiques. Les résultats de cette étude devraient fournir une réponse satisfaisante à la question, jusqu’à présent sans réponse, du comportement des limons pendant les séismes.
