Question: What is the primary cause of bearing capacity failure in sandy soils during seismic events?

Options:

Correct Answer: Liquefaction

Solution:

Liquefaction is the primary cause of bearing capacity failure in sandy soils during seismic events, as it can lead to a sudden loss of strength.

What is the primary cause of bearing capacity failure in sandy soils during seismic events?

Step 1: Understand what bearing capacity means. It refers to the ability of soil to support the weight of structures.
Step 2: Learn about sandy soils. These are soils made up of small particles that can easily move around.
Step 3: Know what seismic events are. These are natural occurrences like earthquakes that shake the ground.
Step 4: Discover what liquefaction is. It happens when saturated sandy soil loses its strength and behaves like a liquid during shaking.
Step 5: Realize that during an earthquake, the shaking can cause the water in sandy soils to push the sand particles apart, leading to liquefaction.
Step 6: Understand that when liquefaction occurs, the soil can no longer support structures, causing bearing capacity failure.
