Question-Answer:

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

• (a) The soil is non-homogeneous
  
• (b) The soil particles and water are incompressible
  
• (c) The partial deformation of soil is due to partial change in volume
  
• (d) Coefficient of permeability is variable during consolidation

Ans. (b)

• Soil is homogeneous. • Soil is fully saturated. • Solid particles are incompressible. • Compression and flow are one dimensional. • Strains in the soil are relatively small. • Darcy’s law is valid. • Coefficient of permeability and coefficient of volume compressibility remains constant.
