DYNAMIC AND ECONOMIC DESIGN OF RIGID RETAININGWALL

摘要

A 2-D model which accounts for the effect of coupled sliding and rocking motion and uses strain dependent soil stiffness and material damping for calculating the response of rigid retaining walls subjected to dynamic loads, was developed earlier . This model was used to study the effect inclination of the wall face in contact with the backfill , on its displacement under the effect of ground motions due to Northridge, ElCentro and Loma Prieta earthquakes. The effect of wall inclination on cumulative displacements is discussed and its role in achieving possible cost effectiveness in design of rigid retaining wall is highlighted.
