Question

Given below are two statements:
Statement I: The lateral pressure exerted by the soil when the retaining wall moves away from the back fill, is generally known as active earth pressure of the soil.
Statement II: Rankine's theory of earth pressure assumes that the back of the wall is vertical and smooth.
In light of the above statements, choose the most appropriate answer from the options given below:

• A. Both Statement I and Statement II are correct
• B. Both Statement I and Statement II are incorrect
• C. Statement I is correct but Statement II is incorrect
• D. Statement I is incorrect but Statement II is correct

Hint:

Remember the direction of wall movement:
- Wall moves away from backfill \(\rightarrow\) Active pressure (minimum pressure).
- Wall moves toward backfill \(\rightarrow\) Passive pressure (maximum pressure).
- No wall movement \(\rightarrow\) At-rest pressure.

Answer 1

The Correct Option is A
