Consolidation: Settlement Calculations Flashcards
1
Q
How do you calculate settlement for sandy soil?
A
S=H/Cp*1n(P0+ΔP/P0)
Where:
S = Settlement (m)
C_p = Compression coefficient
H = Soil layer thickness (m)
P_0 = Initial stress (kN/m²)
ΔP = Applied load (kN/m²)
2
Q
Why do smaller calculation steps give more accurate settlement values?
A
Different layers react individually to stress, affecting overall settlement behavior.
3
Q
How does settlement change in the presence of groundwater?
A
Condition - Total Settlement (m)
Dry soil - Lower
Saturated soil -Higher due to reduced effective stress
