Explanation:
Terzaghi's Theory of One-Dimensional Consolidation:
Terzaghi's theory of one-dimensional consolidation is a widely used method to analyze the consolidation settlement of soil. It assumes that the consolidation process occurs only in the vertical direction, neglecting any lateral movement.
Coefficient of Permeability:
In Terzaghi's theory, the coefficient of permeability (k) is considered to be constant throughout the consolidation process. This assumption implies that the permeability of the soil remains unchanged during consolidation.
Importance of Constant Coefficient of Permeability:
- A constant coefficient of permeability simplifies the analysis of consolidation settlement calculations.
- It allows for easier application of the theory in practical engineering problems.
- The assumption of a constant coefficient of permeability is valid for many soils under typical loading conditions.
Limitations of the Constant Coefficient of Permeability:
- In reality, the coefficient of permeability can vary with factors such as stress level, void ratio, and pore fluid composition.
- For more complex soil behavior, it may be necessary to consider variable permeability in the analysis.
Conclusion:
In Terzaghi's Theory of one-dimensional consolidation, the coefficient of permeability is assumed to be constant. While this assumption simplifies the analysis, it is important to recognize its limitations and consider variable permeability for more complex soil conditions.

In Terzaghi’s Theory of one dimensional consolidation, coefficient of permeability is constant during the consolidation. This assumption is made so that not more than one coefficient of permeability is used in the same problem.
