37.9.2. Factors Affecting Residual Strength

Try these first

1. 1.

   What is residual strength?

   Hint

   Think about what happens to soil after a quake.

2. 2.

   Name a factor affecting residual strength.

   Hint

   Reflect on soil characteristics.

3. 3.

   What does residual strength refer to?

   Hint

   Focus on what remains after liquefaction.

4. 4.

   Does higher confining pressure increase residual strength?

   • True
   • False

   Hint

   Think about the structural stability under pressure.

5. 5.

   Given two soil samples from a site, one uniform and the other well-graded, predict how they would behave post-liquefaction regarding residual strength.

   Hint

   Consider how sediment arrangement impacts strength.

6. 6.

   Analyze a scenario where an earthquake induces liquefaction in a construction site. What measures should engineers consider based on residual strength factors?

   Hint

   Think about how soil properties affect building safety.
