Immediate Settlement Calculation
Immediate settlement occurs instantly after load application in all soil types. It’s calculated using elastic theory:
Si = (q × B × I × (1-ν²)) / E
Where: q = applied pressure, B = foundation width, I = influence factor, ν = Poisson’s ratio, E = Elastic modulus

Enter parameters and click calculate to analyze settlement
Calculation Steps:
1. Contact pressure: q = 1000 kN / (2.0 m × 2.0 m) = 250 kPa
2. Elastic settlement: Si = (250 × 2.0 × 0.82 × (1-0.3²)) / 50 = 7.48 mm
Settlement Risk Assessment
Low Risk
Moderate Risk
High Risk
Low Risk
- 0-25 mm: Low risk – acceptable for most structures
- 25-50 mm: Moderate risk – may require special design
- 50+ mm: High risk – requires mitigation measures
