Question

In Terzaghi’s Theory of one dimensional consolidation, the deformation occurs in __________

(a) one direction only

(b) two directions only

(c) three directions only

(d) none of the direction

I had been asked this question in examination.

Enquiry is from Stress Distribution in division Stress Distribution of Geotechnical Engineering I

Answer 1

Right choice is (a) one direction only

The explanation is: In Terzaghi’s Theory of one dimensional consolidation, load is applied in one direction only. Therefore, the deformation also occurs in one direction only. This direction is usually the vertical direction as the load is applied from the top of the sample.
