The factor of safety against bearing failure for a cellular coffer dam embedded in clay is given by:
\( FS = \frac{5.7 \cdot c}{\gamma \cdot H} \)
- Unit cohesion \( c = 60 \, \text{kN/m}^2 \)
- Unit weight \( \gamma = 18 \, \text{kN/m}^3 \)
- Height \( H = 15 \, \text{m} \)
Substituting the values:
\( FS = \frac{5.7 \cdot 60}{18 \cdot 15} = \frac{342}{270} = 1.27 \)
