The objective of this research is to investigate, by means of                   analytical models, the nonlinear response of tied-back flexible                 retaining walls, during seismic events with a view towards developing           rationale methods of design.  To represent different practical                  situations, several anchoring conditions for the tie-rods are                   considered, ranging from a fixed condition to anchors that are allowed          to displace within the soil backfill.  The research will improve the            understanding of the mechanisms, including failure, by which tied-back          walls deform under dynamic loading.  This will identify the conditions          under which it may be desirable to design the wall so that it can               experience permanent displacements, thereby resulting in ground motion          that is less than the peak ground motion.
