37.1.2. Relative Density

Try these first

1. 1.

   What does relative density measure?

   Hint

   Think about how soil packing is described.

2. 2.

   What is a sign of loose soil?

   Hint

   Consider the effects of stress on soil.

3. 3.

   What does low relative density indicate?

   • High resistance to liquefaction
   • Low vulnerability to seismic loading
   • High susceptibility to liquefaction

   Hint

   Think about how packed the soil is.

4. 4.

   Densification of soil leads to reduced void ratio. True or False?

   • True
   • False

   Hint

   Consider the direct result of compaction.

5. 5.

   Design an experiment to test the liquefaction potential of a soil sample with varying relative densities.

   Hint

   Consider controlling variables such as moisture and grain size.

6. 6.

   Evaluate a construction site for liquefaction risks considering its relative density and propose solutions.

   Hint

   Analyze the site's geological history for effective recommendations.
