Variation of Earth Pressure on Retaining Wall for Different Wall Movement

Abstract

Retaining wall is the rigid wall usually constructed to withstand the lateral pressure of soil on their backfill. Thus, retaining wall plays a very important role in many structures considering  economic and safety design of retaining wall depends on proper estimation of earth pressure. In this research paper, FEM based numerical model was developed to estimate the earth pressure for different wall movement conditions. The numerical model results were compared with the experimental model results. The earth pressure on retaining wall for four conditions was analyzed i.e. at rest, h/4, active and passive conditions with varying surcharge loading. The model results show the same trend as of experimental study. Overall from model study in general we can conclude that lateral stress is higher for higher depth as compared with shallow depth.
