A counterfort retaining wall consists of a stem, toe slab, and heel slab as in the case of a cantilever retaining wall. But it also consists of counterforts are regular interval which divides the stem. The stem with the combination of counterfort behaves like a tee-beam with varying width. The stem and heel slabs are effectively fixed to counterforts so that the stem bends horizontally between the counterforts due to lateral earth pressure. Thus the thickness of the stem and the heel slab is considerably reduced due to the reduction of the moment due to the fixity of these slabs between counterforts.
