Question

In Terzaghi’s Theory of one dimensional consolidation, soil particles are ____________ and water is ______________

(a) compressible, incompressible

(b) both are compressible

(c) both are  incompressible

(d) incompressible, compressible

I have been asked this question by my college director while I was bunking the class.

I want to ask this question from Terzaghi’s Theory of One Dimensional Consolidation in chapter One Dimensional Consolidation of Geotechnical Engineering I

Answer 1

Right answer is (c) both are  incompressible

Explanation: In Terzaghi’s Theory of one dimensional consolidation, soil particles and water is considered to be incompressible. Water is slightly compressible. We often treat it as incompressible when doing fluid flow calculations because the pressure changes involved are too small to make an appreciable change to the density.
