37.1.1. Grain Size Distribution

Try these first

1. 1.

   What is liquefaction?

   Hint

   Think about soil behavior during seismic events.

2. 2.

   Define well-graded soils.

   Hint

   Remember the mix of sizes in the soil.

3. 3.

   What type of soil is most susceptible to liquefaction?

   • Well-Graded Soil
   • Fine-Grained Soil
   • Uniform Sand

   Hint

   Consider which soil type has more packing and structure.

4. 4.

   True or False: High plasticity clays are likely to liquefy easily.

   • True
   • False

   Hint

   Think about the properties of clays.

5. 5.

   You are an engineer tasked with designing a foundation in an area prone to earthquakes. Explain how you would evaluate the soil’s grain size distribution and suggest suitable mitigation strategies.

   Hint

   Consider both grain size distribution and the composition of the soil.

6. 6.

   A site features layers of sand varying from uniform to well-graded. How would the response to seismic loading differ between these layers, and what implications does this have for construction?

   Hint

   Reflect on the packing characteristics of different sand types.
