1.4. Primary Consolidation Settlement

Try these first

1. 1.

   What are the three components of total settlement?

   Hint

   Remember the acronym 'IPSC'.

2. 2.

   What happens during immediate settlement?

   Hint

   Think about what happens in the first moments under load.

3. 3.

   What is the primary mechanism of primary consolidation?

   • Particle rearrangement
   • Pore water expulsion
   • Soil density increase

   Hint

   Remember what happens as the load is applied.

4. 4.

   True or False: Primary consolidation is instantaneous.

   • True
   • False

   Hint

   Is it just about time or type of consolidation?

5. 5.

   A building is designed on a saturated clay mass with a given vertical stress. Estimate the consolidation settlement after applying a specified load, including calculations.

   Hint

   Start with the consolidation equation!

6. 6.

   How would you design a foundation considering both primary and secondary consolidation? Discuss factors to be considered in your design.

   Hint

   Integrate both concepts into your engineering design!
