Questions & Step-by-Step Solutions
In a case study, a retaining wall is experiencing lateral earth pressure. Which factor is most critical in determining the wall's stability?
Step 1: Understand what a retaining wall is. It is a structure that holds back soil or rock from a building, structure, or area.
Step 2: Learn about lateral earth pressure. This is the pressure exerted by the soil against the wall, which can push the wall over if it is too strong.
Step 3: Identify the backfill angle. This is the angle at which the soil is placed behind the wall. It can be steep or gentle.
Step 4: Recognize that the backfill angle affects how much pressure the soil exerts on the wall. A steeper angle usually means more pressure.
Step 5: Conclude that the backfill angle is critical for the wall's stability because it directly influences the lateral earth pressure.
