Abstract

An analysis for determination of lateral thrust on a rigid retaining wall with reinforced earth backfill under seismic condition is described in this paper. The backfill is reinforced with horizontally laid unattached strips and an equivalent horizontal static force replaces the dynamic force. A Coulomb wedge is assumed to develop at limiting equilibrium. Analysis indicates substantial reduction in pressures on the wall due to reinforcement. An optimum length of reinforcing strips of 60 percent of height of wall is indicated.

Seismic Pressure Distribution on Retaining Wall with Reinforced Earth Backfill

St. Louis, Missouri

An analysis for determination of lateral thrust on a rigid retaining wall with reinforced earth backfill under seismic condition is described in this paper. The backfill is reinforced with horizontally laid unattached strips and an equivalent horizontal static force replaces the dynamic force. A Coulomb wedge is assumed to develop at limiting equilibrium. Analysis indicates substantial reduction in pressures on the wall due to reinforcement. An optimum length of reinforcing strips of 60 percent of height of wall is indicated.
