Which one of the following is the part of assumptions made by Terzaghi while developing the mathematical statement of the consolidation process?

Explanation:

Assumptions in Terzaghi’s Theory of Consolidation:

1. The soil is homogeneous, isotropic, and fully saturated.
2. Soil particles and pore water are incompressible.
3. The flow of water during the expulsion of pore water occurs only in the vertical direction, that is, consolidation is one-dimensional (1D).
4. The change in the volume of soil due to consolidation is negligible compared to the initial volume of soil.
5. Flow is laminar and Darcy’s law is valid.
6. Permeability is the same throughout the thickness of the compressible soil layer.
7. The coefficient of volume compressibility, mv, remains constant with time.
8. Compression takes place only due to the expulsion of pore water, that is, the initial and secondary consolidation is neglected.
9. The coefficient of consolidation for a given soil and site conditions is assumed to be constant.
