Question

When retaining wall moves away from the backfill, the pressure exerted on the wall is known as

• A. Passive earth pressure
• B. Swelling pressure
• C. Pore pressure
• D. Active earth pressure

Hint:

Active earth pressure is caused by the outward movement of the wall, while passive earth pressure occurs when the wall moves inward.

Answer 1

The Correct Option is D

When a retaining wall moves away from the backfill, the soil experiences a decrease in stress, resulting in a condition called active earth pressure. This is the pressure exerted by the soil when the wall moves outward. Hence, the correct answer is "Active earth pressure".
