3.1. Internal Stress Application

Try these first

1. 1.

   What is the primary purpose of bentonite slurry in pile installation?

   Hint

   Think about materials used in construction.

2. 2.

   What is pre-stressing?

   Hint

   Focus on the timing of stress application.

3. 3.

   What is the main advantage of pre-stressed piles?

   • A) More complex to build
   • B) Increases load-bearing capacity
   • C) Lower costs than conventional piles

   Hint

   Consider what pre-stressing is applied for.

4. 4.

   True or False: Precast piles can easily be modified at the construction site.

   • True
   • False

   Hint

   Remember the limitations of precast structures.

5. 5.

   A construction site located near water is preparing to install piles. Discuss how bentonite slurry could specifically aid in this context and what factors the engineers should consider.

   Hint

   Think about the effects of water on soil stability.

6. 6.

   Consider a project requiring piles longer than 30 meters. Explain the implications of using traditional concrete piles versus pre-stressed concrete piles.

   Hint

   Focus on the materials’ properties and their limits.
