Step 1: Find the resultant earth pressure. K a = tan 2 ( 45 − φ / 2) = tan 2 ( 45 − 30 / 2) K a = tan 2 ( 30) = 0.33. Earth pressure at the bottom of the base = KaγH = 0.33 × 17.3 × 10 = 57.1 kN/m 2. Resultant earth pressure ( F) = area of the pressure triangle = 57 .1 × 10/2 = 285 .5 kN per meter length of the wall.
