Mechanism of Failure:
The shapes of the failure surface under ultimate loading conditions.
The zones of plastic equilibrium represented in this figure by the area may be subdivided into three zones:
1 . Zone I of elastic equilibrium
2. Zones II of radial shear state
3. Zones III of Rankine passive state
When load qu per unit area acting on the base of the footing of width B with a rough base is transmitted into the soil, the tendency of the soil located within zone I is to spread but this is counteracted by friction and adhesion between the soil and the base of the footing.
Due to the existence of this resistance against lateral spreading, the soil located immediately beneath the base remains permanently in a state of elastic equilibrium, and the soil located within this central Zone I behaves as if it were a part of the footing and sinks with the footing under the superimposed load.

Introduction to Terzaghi's Bearing Capacity Theory
In Terzaghi's theory of bearing capacity for shallow foundations, understanding the behavior of soil zones beneath the foundation is crucial. One of the key zones identified by Terzaghi is the Zone of Elastic Equilibrium.
Zone of Elastic Equilibrium
- The **Zone of Elastic Equilibrium** is where the soil behaves elastically under applied loads. This zone is critical because:
- It allows for the distribution of stress from the foundation to the surrounding soil.
- It provides a more realistic assessment of how loads are transferred and how soil behaves under load.
Assumption of the Zone as Part of the Footing
- In Terzaghi's analysis, this zone is assumed to act as if it were part of the footing due to the following reasons:
- **Stress Distribution**: The elastic behavior of this zone helps in understanding how the stresses are distributed beneath the foundation.
- **Load Transfer Mechanism**: The zone participates actively in load transfer, affecting the overall bearing capacity.
- **Foundation Interaction**: It illustrates the interaction between the foundation and the soil, which is vital for evaluating stability and settlement.
Conclusion
In summary, the Zone of Elastic Equilibrium is a fundamental part of Terzaghi's theory as it directly influences the bearing capacity and performance of shallow foundations. Understanding this zone allows engineers to design safer and more efficient foundations by accurately predicting how the soil will react to loads.
