ABSTRACT:
A retaining wall or a counterfort retaining wall incorporates a vertical stem wall section, a base section having a toe, a heel, and a number of shallow piles at the bottom of the base section to improve the sliding and overturning safety factor of the wall. To further improve the sliding and overturning safety factor of the wall, an edge of the heel is slanted with a bevel or a batter with an angle to pick up more resisting load.
