INTERACTION BETWEEN A THIN RETAINING WAL WITH BACKFILL IN THE PRESENCE OF THE RIBS OF INFLEXIBILITY

The question of the definition of lateral earth pressure on a thin retaining wall with buttresses (ribs), arranged from the side of a gravel backfill was considered. Laboratory experimental researches were carried out during the solution of given tasks. Researches were fulfilled in a soil tray models steel retaining wall with ribs of different configurations. The dependence of the lateral earth pressure on a thin retaining wall from the geometric parameters of the buttress was established. The laboratory results are presented as curves of lateral earth pressure and displacement of the wall height. The accuracy of the obtainred results was justified by the implementation of numerical experiments and mathematical modeling.
