Environmental Impact on the Stability of Dey Palace in the Casbah of Algiers

Abstract eng:
Cultural heritage is a fundamental part of the history and identity of societies; it contributes to the preservation of their memory and their welfare. This heritage, which cannot be estimated economically, must be protected against all risks whether natural or caused by human activity. The Citadel of Algiers (Casbah) is composed of several buildings, the main one being the Palace of Dey, which is classified as historical monument. It is a set constituted by imposing civilian and military buildings. The Citadel has a total area of 9000 m2 where 7500 m2 are occupied by buildings. Its construction dates back to the early XVIth Century. The purpose of this work is to study the impact of car traffic in Mohamed Taleb Street, which crosses the citadel, on the Palace of Dey in order to take the necessary protective measures if the vibrations generated by this traffic prove harmful to structure of the building. The analysis, carried out using ambient vibrations recordings performed continuously for 21 hours, showed that there is a significant impact on the Palace of Dey structure due to car traffic in Mohamed Taleb Street.
