The various forces acting on a cantilever sheet pile wall are the active earth pressure on the back of the wall and the passive earth pressure on the front of the wall.
The theory behind the design including soil structure interaction and three dimensional considerations is so complex that an exact design is not even attempted when designing sheet pile walls by hand.
The design of sheet pile walls is a very complex undertaking.
Cantilever walls are walls that do not have any supports and thus have a free unsupported excavation.
