37.4.3. Types of Liquefaction

Try these first

1. 1.

   What occurs during flow liquefaction?

   Hint

   Think about what happens when shear stress is too high.

2. 2.

   Define lateral spreading.

   Hint

   Consider how lateral forces might affect the ground.

3. 3.

   What happens during flow liquefaction?

   • Soil becomes more compact
   • Soil flows like a liquid
   • Soil gains strength

   Hint

   Think about the effects of excessive stress.

4. 4.

   True or False: Cyclic liquefaction occurs only during large earthquakes.

   • True
   • False

   Hint

   Recall that it's the build-up over time that leads to this condition.

5. 5.

   Analyze how different soil types influence the susceptibility to flow and cyclic liquefaction.

   Hint

   Factor in soil density and saturation levels in your analysis.

6. 6.

   Devise a strategy to mitigate the risks of lateral spreading in an urban area.

   Hint

   Think about both short-term and long-term structural techniques.
