Summary

In East and Middle Anatolia, where several heavy industrial plants are planned to be constructed, vast areas are covered by gypsiferous layers. In this investigation, geotechnical properties of the gypsum layer, encountered at the Sivas IVth Iron and Steel Complex Site, are investigated and an attempt is made to propose solutions to some of the geotechnical problems anticipated at the site. In the research several physical, chemical and engineering properties of gypsum, the changes caused by the environmental conditions on its mechanical behaviour and crystal structure, its stress-strain-time behaviour and effect on foundation concrete are investigated and recommendations on the precautions to be taken are presented.

Influence de la presence de gypse sur la conception des fondations

Résumé

Une très grande partie de l'Anatolie centrale et orientale où la construction de diverses usines industrielles est en cours de planification, est couverte de couches gypsifères. Cette recherche a été faite dans le but de trouver les propriétés géotechniques de la roche-mère gypsifère du site de la 4ème usine sidérurgique de Sivas et aussi de résoudre en partie les problèmes éventuels y afférant. Dans cette recherche ont été étudiées les propriétés physiques, chimiques et mécaniques du gypse ainsi que les modifications dérivant de sa structure cristalline en milieux variés, le comportement de “tension-déformation-temps” et son influence sur le béton de la base. Les mesures nécessaires à prendre ont aussi été conseillées.
