For a cellular coffer dam embedded in clay, what will be the factor of safety against bearing failure?

(Consider height of cell above the top of the stratum H = 15 m, unit cohesion c = 60 KN/m2 and unit weight of cell fill y = 18 KN/m2)

Concept:

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:

\( FS = \frac{5.7 \cdot 60}{18 \cdot 15} = \frac{342}{270} = 1.27 \)
