A New Approach for Estimating the Seismic Soil Pressure on Retaining Walls


Department of Civil Engineering,Sharif University of Technology


The model incorporates nonlinearity in the behavior of near wall soil, wall
exibility and
elastic free eld soil response. This model can be employed in nonlinear modeling of retaining walls and
bridge abutments. The advantages of this model are simplicity and
exibility in addition to acceptable
precision. Using this nite element model, an analytical study is conducted on several soil-wall systems
using nonlinear time-history analysis by applying real earthquake records. Based on the results of these
analyses, new seismic soil pressure distributions are proposed for di erent soil and boundary conditions.
These distributions are shown to be more accurate than the popular Mononobe-Okabe equations.
