37.1. Soil Properties Affecting Dynamic Behavior

Try these first

1. 1.

   What is a key effect of grain size distribution in soils?

   Hint

   Think about how tightly packed the soil is.

2. 2.

   How does relative density influence liquefaction potential?

   Hint

   Consider how density relates to packing.

3. 3.

   Which type of soil is most susceptible to liquefaction?

   • Well-graded sand
   • Uniform sand
   • Clay

   Hint

   Consider the arrangement of particle sizes.

4. 4.

   True or False: High void ratios directly increase resistance to liquefaction.

   • True
   • False

   Hint

   Think about how packing affects soil strength.

5. 5.

   Consider a saturated sandy soil with a high void ratio subjected to an earthquake. Discuss the expected behavior and factors that contribute to its liquefaction potential.

   Hint

   Consider how pore pressure and void ratios interact.

6. 6.

   Evaluate a site with well-graded silt near a shallow groundwater table. How would you assess its liquefaction risks compared to a site with uniform sand under similar conditions?

   Hint

   Think about the differences in soil types specifics.
