37.10.3. Rebuilding Shear Strength

Try these first

1. 1.

   What happens to shear strength during liquefaction?

   Hint

   Think about how liquids behave.

2. 2.

   Can soil regain strength after liquefaction?

   Hint

   What happens when water in soil drains?

3. 3.

   What happens to the shear strength of soil during liquefaction?

   • It increases
   • It decreases
   • It stays the same

   Hint

   Remember how liquids behave under stress.

4. 4.

   True or False: The original soil structure is always regained after liquefaction.

   • True
   • False

   Hint

   Think about how materials can change when stressed significantly.

5. 5.

   A foundation constructed on a site susceptible to liquefaction experiences an earthquake. Outline the steps an engineer should take post-event regarding the soil and structure analysis.

   Hint

   Follow a logical sequence of steps from inspection to redesign.

6. 6.

   Discuss how community infrastructure (like roads and bridges) should be assessed after a liquefaction event. Identify key structural considerations.

   Hint

   Think about how structures interact with ground movements.
