ANALYSIS OF EARTH PRESSURE AT RETAINING WALLS REINFORCED WITH GEOSYNTHETICS

Abstract

Recent design methods of reinforced retaining walls are based on several approaches at the earth pressure determination. Newer methods are developed to bring the design model closer to real conditions. The monitoring of the structures reinforced with the geosynthetics but shows some anomalies at wall displacements and reinforcement loads. A series of real structure monitoring and numerical modelling was involved to verify the recent design methods. This paper represents the results of these analyses aimed at the earth pressure due to the backfill of the wall and at the stress distributions along the reinforcements.
