15.4 Repeat Problem 15.3, using Coulomb's active earth pressure
in your calculation and letting 8' = 2/36.
A gravity retaining wall is shown in Figure P15.3. Calculate
the factor of safety with respect to overturning and sliding,
given the following data:
Wall dimensions:
H=6m, x₁ = 0.6 m, x₂ = 2 m,
x3 = 2 m, x4 = 0.5 m, xs = 0.75 m,
x6 =0.8 m, D= 1.5 m
Soil properties:
Y2
=
16.5 kN/m²,
= 32°,
=
18 kN/m²,
= 40 kN/m²
= 22°,
Use the Rankine active earth pressure in your calculation.
