Retaining wall movements due to deep excavation in Zagreb

In this paper several case studies of deep excavations in Zagreb are presented, containing the basic information of retaining structure geometry, geotechnical profile and inclinometer measurements. Horizontal displacements of the retaining structure are analyzed taking into account dimensions of the excavation pit and retaining structure, geotechnical soil profile, safety factor of base heave, stiffness of the retaining wall and stiffness of the complete retaining structure together with geotechnical anchors. The analysis has been performed according to the well established method proposed by Bjerrum & Eide 1956, Clough et al. 1989 and Clough & O’Rourke 1990. The results are compared to database of around 300 retaining walls from all over the world, summarized by Long 2001.
