37.6. Evaluation of Liquefaction Potential

Try these first

1. 1.

   What does SPT stand for?

   Hint

   Think of a common field test for soils.

2. 2.

   What is the purpose of the Cone Penetration Test?

   Hint

   It's a test using a cone!

3. 3.

   What does SPT measure in soil?

   • Soil density
   • Soil resistance to penetration
   • Shear strength

   Hint

   It's about how well soil holds up against being pushed.

4. 4.

   True or False: A Factor of Safety less than 1 indicates a lower risk of liquefaction.

   • True
   • False

   Hint

   Think about what a safety factor under 1 suggests.

5. 5.

   Given a site with a high corrected N-value from SPT and low ratings from CPT, predict the liquefaction potential and justify the reasoning.

   Hint

   Consider the relationship between the two test results and contextual implications.

6. 6.

   Design a study comparing the effectiveness of cyclic triaxial tests versus cyclic simple shear tests in assessing liquefaction susceptibility. What parameters are critical?

   Hint

   Explore how each method provides insights into soil behavior differently.
