Question

If $\Delta p$ is increment of pressure on a normally consolidation saturated soil mass, as per Terzaghi's theory at the instant of application of pressure increment i.e., when time t = 0, what is the pore pressure developed in the soil mass?

• A. Zero
• B. Very much less than $\Delta p$
• C. Equal to $\Delta p$
• D. Greater than $\Delta p$

Answer 1

The correct option is C Equal to $\Delta p$

At t = 0 the pore pressure increment or pore pressure developed will be $\Delta p$. At any time t > 0 excess pore pressure dissipates and reduces.
