Questions & Step-by-Step Solutions
What is the effect of foundation depth on bearing capacity in cohesive soils?
Step 1: Understand what cohesive soils are. These are soils that stick together, like clay.
Step 2: Learn about bearing capacity. This is the ability of the soil to support weight without collapsing.
Step 3: Know what foundation depth means. This is how deep the base of a building or structure is placed into the ground.
Step 4: Realize that as you go deeper into the soil, the weight of the soil above increases.
Step 5: Understand effective stress. This is the pressure that contributes to the soil's ability to support weight, which increases with depth.
Step 6: Conclude that in cohesive soils, as the foundation depth increases, the bearing capacity also increases because of the higher effective stress.
