26.10.3. Liquefaction and Wave Behavior

Try these first

1. 1.

   What happens to saturated soils during liquefaction?

   Hint

   Think about what happens when water saturates soil.

2. 2.

   True or False: Liquefaction can occur in dry soils.

   Hint

   Recall the definition of liquefaction.

3. 3.

   What is liquefaction?

   • A solid ground condition
   • Soil turning to a liquid
   • A type of wave behavior

   Hint

   Remember the definition of liquefaction.

4. 4.

   True or False: Liquefaction can only occur in saturated, loose sands.

   • True
   • False

   Hint

   Think about the conditions required for liquefaction.

5. 5.

   Consider a hypothetical town built on loose, saturated sand near a fault line. Describe the steps that structural engineers would take to assess liquefaction risk in this area.

   Hint

   Think about both physical investigations and analytical data.

6. 6.

   A building in a liquefied area experienced significant lateral displacement. Discuss potential failures in structural design that might have contributed to the facility's damage.

   Hint

   Consider what engineers can evaluate before construction to improve resilience.
