1.2.2. Under Consolidated Soils

Try these first

1. 1.

   What is preconsolidation pressure?

   Hint

   Think about what stress the soil holds in memory.

2. 2.

   Name the three types of soils based on stress history.

   Hint

   Recall the classifications discussed in class.

3. 3.

   What does preconsolidation pressure signify in soil mechanics?

   • Internal friction
   • Maximum effective stress
   • Cohesive strength

   Hint

   Think about the stress levels soil can handle.

4. 4.

   True or False: Normally consolidated soils have never been subjected to a stress greater than the current effective stress.

   • True
   • False

   Hint

   Consider what 'normally' means.

5. 5.

   You are tasked with a construction project over an area known to have under consolidated soils. What steps will you take to ensure safety and stability?

   Hint

   Consider logistical options before construction.

6. 6.

   Analyze the potential risks involved with building on over consolidated soils. What measures can mitigate these risks?

   Hint

   Think about unexpected soil behaviors.
