In terms of the bearing resistance limit state, the design is satisfactory since the maximum bearing pressure (153.6 kN/m2) is less than the allowable bearing capacity (250 kN/m2).

Sliding

Using Rankine's theory (with <j>' = 38°) Ka = 0.238

Active thrust from soil,

Active thrust due to surcharge,

SH = 65.5 kN Total force causing sliding, Rh = 65.5 kN Force resisting sliding = Rvtan<5 = 267.9 x tan 38° = 209.3 kN
