MODEL TEST AND EARTH PRESSURE CALCULATION OF A GRAVITY RETAINING WALL WITH A RELIEVING PLATFORM

By using aluminum cylindrical rods instead of sand as backfill material, model tests were made to investigate the characteristics of the sliding surfaces in the backfill behind a gravity retaining wall with a relieving platform and the influence of a strip surcharge on the locations of the critical sliding surfaces. Results indicate that there is an outer (second) sliding surface that should be taken into account in computing the earth pressure on the wall above the platform. Based on Coulomb's theory and considering the existence of such a sliding surface, various formulas are derived for determining the critical angles of inclination of the sliding surfaces and the corresponding earth pressure. Various boundary equations for determining the ranges of locations of the critical sliding surfaces are derived. These formulas and equations can also be applied to the case of surcharged walls.
