CLSM Lateral Pressure - Earth retention engineering - Eng-Tips

If for reduction of lateral pressure, the ground surface between the fill and the original ground should be sloped. Whichever fill you install, it will be rigid. If retained soils push laterally on the rigid fill, the soil will push on the fill and the fill, therefore, will push on the structure.

Backfill with cellular concrete behind a soldier pile wall ...

Cellular concrete with a relatively small density exerts a much smaller lateral pressure on the soldier pile wall. The cellular concrete behaves more like a solid mass that has the potential to slide on the existing slope and as a result the overall lateral load on the soldier piles is greatly reduced.
