3.2. Concrete Piles

Try these first

1. 1.

   What are the two types of methods used for installing concrete piles?

   Hint

   Think about how much soil is disturbed during installation.

2. 2.

   Name one advantage of concrete piles over timber piles.

   Hint

   Consider the material properties.

3. 3.

   What type of installation method significantly disturbs surrounding soil?

   • Displacement Method
   • Non-Displacement Method
   • Both

   Hint

   Think about what happens to soil when the pile is driven.

4. 4.

   True or False: Concrete piles are more susceptible to decay than timber piles.

   • True
   • False

   Hint

   Reflect on the properties of each material.

5. 5.

   Given a soil profile with varying layers, design a foundation for a hypothetical building using both friction and end bearing piles.

   Hint

   Consider soil characteristics and how they influence pile choice.

6. 6.

   Analyze the impact of increasing pore pressure during displacement pile installation and devise a mitigation strategy.

   Hint

   Think about how gradual changes can help stabilize soil around installed piles.
