Evaluation of Active Earth Pressure behind Retaining Walls with Lateral Movements under Cyclic Loading

Authors

Abstract

To have a more clear judgment about distribution and point of application of active earth pressure behind retaining walls, simultaneous studies on both physical and numerical models are required. In this study the behavior of backfill soil under static and cyclic surcharges has been evaluated using the FLAC software while the wall has some lateral movements. To verify the numerical model the results have been compared with those measured behind the same physical model developed in soil mechanics laboratory of Amirkabir University of Technology. After that an extensive parametric studies have been carried out to investigate the influences of different factors such as amplitude, position and type of surcharges as well as backfill soil properties and the amount of the wall movements. The results of these studies have been explained and discussed in different section of the present paper.
