Monitoring, Back analysis and Redesign of a Deep excavation Retaining system in marl formation. Case history, Modelling and Interpretation
Lebanese University, Faculty of engineering, Roumieh, Lebanon
We present in this paper a case study of retaining system of a deep excavation in a marly material in Beirut. The retaining system was redesigned using a new set of mechanical parameter considered more realistic than the set issued from the site investigation study. The new values were issued from back analysis of displacements measurement performed in the same site. The horizontally deflection of the retaining system was measured using three vertical inclinometers. The experimentation results are simulated by numerical calculation using finite elements code.
