Question

Consider the following statements:
1. Pore pressure parameter A is a constant for a soil.
2. The shear strength of soil is a function of the effective stress in the soil and not of the total stress in the soil.
Which of these statements is/are correct?

• A. $1$ Only
• B. $2$ Only
• C. Both $1$ and $2$
• D. Nether $1$ nor $2$

Answer 1

The correct option is B $2$ Only

Pore water parameters are empirical coefficients which are used to express the response of pore pressure to changes in total stress under undrained conditions. Pore pressure parameter A is not a constant and is different for different soils and stress conditions. For a given soil, A depends upon the strain, anisotropy, sample disturbance and the over consolidation ratio.
