Result Interpretation

Oedometer-Based 1D Consolidation Settlement (Logarithmic Compression) calculator computes Consolidation Settlement in m using the defined engineering formula and the input values provided. Consolidation Settlement is expressed in m. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Compression Index = 0.25
  • Initial Void Ratio = 0.8
  • Initial Thickness = 5
  • Initial Vertical Effective Stress = 100
  • Incremental Vertical Effective Stress = 50

Expected Result:

  • Consolidation Settlement = 0.28157299174178

Engineering Interpretation:

Under the given input conditions, the calculated result is: Consolidation Settlement = 0.28157299174178 m.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.

Formula / Method

consolidation settlement = (compression index / (1 + initial void ratio)) * initial thickness * log((initial vertical effective stress + incremental vertical effective stress) / initial vertical effective stress)
