37.1.7. Soil Fabric and Structure

Try these first

1. 1.

   What is soil fabric?

   Hint

   Think about how particles are organized.

2. 2.

   Why are remolded soils more susceptible to liquefaction?

   Hint

   Consider what happens when soil is disturbed.

3. 3.

   What happens to soil structure during liquefaction?

   • It becomes more stable
   • It behaves like a fluid
   • It becomes stronger

   Hint

   Remember the fluid analogy.

4. 4.

   True or False: Cemented soils are always resistant to liquefaction.

   • True
   • False

   Hint

   Consider the limits of strength.

5. 5.

   Discuss the geological mechanisms that lead to the formation of cemented soils and why they are effective against liquefaction.

   Hint

   Consider natural processes and their role in particle stability.

6. 6.

   Propose a strategy to mitigate liquefaction risks in areas with predominately loose, remolded soils.

   Hint

   Think about construction techniques that enhance soil strength.
