6. Preconsolidation Pressure
The chapter provides an overview of preconsolidation pressure, the maximum effective stress experienced by soil throughout its stress history, and classifies soils based on their stress history: normally consolidated, over consolidated, and under consolidated soils. The behavior of these soils under various loading conditions and their implications for structural integrity are emphasized.

What we have learnt
- Preconsolidation pressure indicates the past maximum effective stress on a soil.
- Soils can be classified into normally, under, and over consolidated based on their stress history.
- Under consolidated soils can undergo significant deformation, posing risks to structures.
Key Concepts
- -- Preconsolidation Pressure
- The maximum effective stress that a soil has experienced in its stress history.
- -- Normally Consolidated Soils
- Soils that have never experienced a vertical effective stress greater than the current stress.
- -- Over Consolidated Soils
- Soils that have experienced vertical effective stress greater than the current effective stress.
- -- Under Consolidated Soils
- Soils that have not consolidated under the current overburden pressure and are prone to larger deformations.
