Cantilever retaining wall: base slab designed as a cantilever under upward soil pressure (net upward pressure = gross bearing pressure − slab self weight − soil weight above slab). Toe: designed for net upward pressure; heel: designed for the difference between soil overburden and net bearing reaction. Maximum BM at stem-base junction.
