Lateral earth pressure is the pressure that soil exerts against a structure in a sideways, mainly horizontal direction. Since most open cuts are excavated in stages within the boundaries of sheet pile walls or walls consisting of soldier piles and laggings and since struts are inserted progressively as the excavation proceeds, the walls are likely to deform (as shown in the figure).
Little inward movement can occur at the top of the cut after the first strut is inserted. As the earth pressure magnitude increases due to an increase in effective stress while moving from top to bottom, so deflection of a sheet pile in a braced cut increases from top to bottom.
