ABSTRACT
The pressure distribution on the wall is shown in Fig. II.II(b). The active pressure at depth H is
Pa =yHKA which acts parallel to the surface. The total pressure Pa per unit length of the wall is
1P =-yH2K a 2 A (11.25)
which acts at a height H/3 from the base of the wall and parallel to the sloping surface of the backfill.
