FIGURE 8.10 Charts for estimating Rankine active earth pressures against retaining walls supporting
sloped ground of limited height. Notes: (1) Soil types shown on curves correspond to soil types
described in Table 8.1. (2) For soil type 5, computations of soil pressure may be based on a value of H
4 ft (1.2 m) less than the actual value. (3) The minimum value of kh for design should be 35 lb/ft2/lin ft
(5.50 kN/m2/m). (4) Add pressures due to water and surcharge (including 2 ft minimum soil surcharge)
to the active earth pressures from these charts. (From Design Manual, Part 4, Pennsylvania Department
