Rise of water table above the ground surface causes-
  • a)
    Equal increase in pore water pressure and total stress
  • b)
    Equal decrease in pore water pressure and total stress
  • c)
    Increase in pore water pressure but decrease in total stress
  • d)
    Decrease in pore water pressure but increase in total stress
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
Rise of water table above the ground surface causes-a)Equal increase ...
A rise increases the pore water pressure at all elevations thus causing a decrease in effective stress. A rise above ground surface increases both the total stress and the pore water pressure by the same amount, and consequently effective stress is not altered.
Hence, the correct option is (A).

Rise of water table above the ground surface causes-a)Equal increase ...
Introduction:
The rise of the water table above the ground surface can have several effects on the soil and its properties. In this case, we are considering the impact on pore water pressure and total stress.

Explanation:
When the water table rises above the ground surface, it exerts pressure on the soil particles and fills the voids between them. This increase in water pressure affects the overall behavior of the soil, including the pore water pressure and total stress.

Pore Water Pressure:
Pore water pressure is the pressure exerted by the water in the soil voids. When the water table rises, it increases the pore water pressure in the soil. This is because the water exerts additional pressure on the soil particles and fills the voids, leading to an increase in the pore water pressure.

Total Stress:
Total stress is the sum of the weight of the soil particles and any additional pressure applied to the soil. When the water table rises, it adds additional pressure to the soil. This increase in pressure results in an increase in the total stress acting on the soil.

Equal Increase:
In this case, the rise of the water table above the ground surface causes an equal increase in both pore water pressure and total stress. This means that the additional pressure exerted by the water on the soil particles is distributed evenly between the pore water and the solid particles, resulting in an equal increase in both.

Reasoning:
The equal increase in pore water pressure and total stress can be attributed to the fact that the water fills the voids in the soil and exerts pressure on both the soil particles and the pore water. This increase in pressure is distributed evenly, leading to an equal increase in both pore water pressure and total stress.

Conclusion:
In conclusion, the rise of the water table above the ground surface causes an equal increase in pore water pressure and total stress. This is because the additional pressure exerted by the water is distributed evenly between the pore water and the solid particles in the soil.
