Mathematics · Soil Mechanics - Compressibility
In a consolidation test, the void ratio is found to be 0.98 under an effective pressure of 194 kN/m2. Later, the void ratio reduces to 0.89 when the pressure is increased to 400 kN/m2. The coefficient of compressibility (av) is:
- 18.36 × 10-3 m2/kN
- 26.38 × 10-5 m2/kN
- 34.37 × 10-4 m2/kN✓
- 42.39 × 10-2 m2/kN
Correct answer
4.37 × 10-4 m2/kN
