Question

Terzaghi's one-dimensional consolidation theory assumes that

• A. $e{v}_{s}p$ relationship is linear
• B. $e{v}_{s}lo{g}_{10}p$ relationship is linear
• C. $p{V}_{s}lo{g}_{10}e$ relationship is linear
• D. $e{v}_{s}lo{g}_{10}\frac{p}{p_0}$ relationship is linear

Answer 1

The correct option is A $e{v}_{s}p$ relationship is linear

Terzaghi's one-dimensional consolidation theory assumes that coefficient of compressibility ($a_v)$ is constant throughout the soil.

Coefficient of compressibility is the slope of e v/s P plot. Hence the $a_v$ to be constant e v/s P relationship is linear.


$a_v=\frac{e_1-e_2}{P_2-P_1}$

$a_v=\frac{\Delta e}{\Delta P}$
