A reinforced concrete retaining wall is proportioned as shown below. There is a water table located H1m beneath the ground surface. Use ultimate bearing capacity of 450 kPa.

Based on the figure, the dimensions are given below. Use γc = 23.48 kN/m3

  • wall thickness = 0.47m
  • footing thickness = 0.53m
  • toe slab length = 2.33m
  • heel slab length = 4.38m
  • ground water table depth = 2.99
  • H2 = 3.84

The following values were calculated for this particular retaining wall:

  • Righting moment: 3,868 kN-m/m
  • Overturning moment: 908 kN-m/m
  • Total vertical load: 999 kN/m

What is the factor of safety for bearing pressure?
