If the water table rises upto ground surface, then the
  • a)
    effective stress is reduced due to decrease in total stress only but pore water pressure does not change
  • b)
    effective stress is reduced due to increase in pore water pressure only but total stress does not change
  • c)
    total stress is reduced due to increase in pore water pressure only but effective stress does not change
  • d)
    total stress is increased due to decrease in pore water pressure but effective stress does not change
Correct answer is option 'B'. Can you explain this answer?

Explanation:

When the water table rises up to the ground surface, the soil pores become fully saturated with water. This leads to an increase in pore water pressure, which affects the effective stress and total stress of the soil.

Effective Stress:

Effective stress is defined as the difference between the total stress and the pore water pressure. When the water table rises, the pore water pressure increases, which reduces the effective stress.

Total Stress:

Total stress is defined as the sum of the effective stress and the pore water pressure. When the water table rises, the total stress remains constant because the increase in pore water pressure is offset by the decrease in effective stress.

Therefore, option B is the correct answer as the effective stress is reduced due to an increase in pore water pressure only, but the total stress does not change.

In summary:

- Rising water table leads to fully saturated soil pores
- Increases pore water pressure
- Reduces effective stress
- Total stress remains constant as increase in pore water pressure is offset by decrease in effective stress
