37.5. Factors Influencing Liquefaction Potential

Try these first

1. 1.

   What is liquefaction?

   Hint

   Think about what happens to wet sand at the beach when it's shaken.

2. 2.

   Name one factor affecting liquefaction potential.

   Hint

   Consider what you learned about seismic events and soils.

3. 3.

   What is the relationship between peak ground acceleration and liquefaction potential?

   • A. Higher PGA decreases liquefaction potential
   • B. Higher PGA increases liquefaction potential
   • C. PGA has no impact on liquefaction potential

   Hint

   Think about how shaking affects the soil.

4. 4.

   True or False: A higher relative density decreases the likelihood of liquefaction.

   • True
   • False

   Hint

   Consider what happens to loose versus dense soils.

5. 5.

   Evaluate a site with a shallow water table and loose sandy soil. What interventions might you recommend to mitigate liquefaction risk during an earthquake?

   Hint

   Consider different engineering strategies for soil stabilization.

6. 6.

   Discuss how the characteristics of a site can change the liquefaction potential based on your knowledge of the seismic factors. Create a checklist of factors to evaluate.

   Hint

   Identify parameters that can lessen or heighten liquefaction risks.
