SEISMIC DESIGN OF REINFORCED EARTH WALLS-DISCUSSION

The authors discuss a well documented case history of the performance of a 3.75-m high reinforced earth retaining wall (supports a railway embankment fill) described by discussers. This wall tilted out at the top about 10 cm during construction and another 10 cm during the first 4 months after completion. Post construction vertical settlement of the backfill was about 20 cm. The authors agree that much of the post-construction movement was due to vibration from the trains passing over the backfill. The lateral pressures during vibrations are greater than k sub a conditins, and the danger of the tie pull out failure could be reduced by using small plates at the ends of the ties. Comments are also made on the tie pullout and noncollapse deformation problems.
