Abstract

Rigid retaining walls experience significant displacements during earthquakes. Several investigations have developed 1-D and 2-D models to predict displacements. A critical review of the state of the art shows that these model may not predict realistic displacement Wu (1999). A new 2-D model, which considers strain dependent soil stiffness and material damping, sliding and rocking motions, and practical field water conditions behind the wall as per Eurocode (1994) have been presented. Typical results are included. A comparison of prediction and performance of a centrifuge model has shown good agreement. This model represents a considerable advance over the existing solutions and is easily useable by the practicing engineer.

Seismic Displacements of Rigid Retaining Walls

San Diego, California

Rigid retaining walls experience significant displacements during earthquakes. Several investigations have developed 1-D and 2-D models to predict displacements. A critical review of the state of the art shows that these model may not predict realistic displacement Wu (1999). A new 2-D model, which considers strain dependent soil stiffness and material damping, sliding and rocking motions, and practical field water conditions behind the wall as per Eurocode (1994) have been presented.
