Abstract

A geotechnical investigation comprising percussion drilled boheroles and trial pits and field and laboratory index engineering tests were carried out in a highly weathered gneissic rock in Tema-Ghana. On the basis of this investigation, a DEEP BLOCK FOUNDATION was selected for a hammer in a forging factory.

The effect of embedded foundations on vibrations has been highlighted in the paper.

Computation of settlements of the selected foundation and that of the other structures could not be discussed in detail due to the lack of technical data relating to the actual hammer to be used.

Étude géotechnique en vue du choix des fondations pour un marteau pilon, dans des gneiss très altérés du ghana

Résumé

Une étude géotechnique incluant des forages par percussion et des puits d'essai, ainsi que des essais in situ et en laboratoire a été réalisée en vue du choix des fondations pour un marteau pilon dans une usine métallurgique. Les terrains, situés à Tema, au Ghana, sont constitués de gneiss très altérés. Le choix s'est arrêté sur une fondation profonde. L'article étudie essentiellement l'effet des fondations enterrées sur les vibrations. Les tassements de la fondation et des autres structures n'ont pas été étudiés en détail, les caractéristiques précises du marteau pilon prévu n'étant pas connues.
