In one-dimensional consolidation theory, the coefficient of consolidation mainly governs the:
Correct answer: A. Rate at which consolidation settlement occurs
- A. Rate at which consolidation settlement occurs
- B. Ultimate consolidation settlement
- C. Shear strength at failure
- D. Initial specific gravity of solids
Explanation
The coefficient of consolidation combines the effects of permeability and compressibility and controls the time rate of excess pore-water pressure dissipation. Ultimate settlement depends mainly on compressibility and the applied stress increase.

About Soil Mechanics and Foundations
Soil mechanics examines index properties, phase relationships, classification, permeability, seepage, compaction, consolidation, shear strength and earth pressure. Foundations apply these principles to bearing capacity, settlement and shallow or deep foundation selection, with clear distinction between compaction, which expels air, and consolidation, which expels water over time.
