DEEP FOUNDATION

Which of the following is an example of a large displacement pile?

• Rotary bored pile

• Micropile

• Spun pile

• Steel H-pile

What type of pile is typically used for deep foundations in soft soil?

• Floating pile

• End-bearing pile

• Auger-cast pile

• Driven pile

What is the primary purpose of using a pile cap?

• To provide lateral stability

• To distribute loads from the superstructure

• To prevent soil erosion

• To increase the bearing capacity of the soil

What is the main advantage of using a driven pile over a bored pile?

• Lower cost

• Better load capacity

• Less noise during installation

• Faster installation

In which scenario would you prefer using a friction pile?

• When soil is very hard

• When soil has low bearing capacity

• When water table is high

• When constructing on rock

What is the primary purpose of a pile shoe?

• To protect the pile during driving

• To facilitate the connection between pile sections

• To extract the pile when needed

• To provide anchorage at the pile head

Which equipment is typically used for driving precast concrete piles?

• Vibratory hammer

• Auger

• 
  Drop hammer

  
  

• Rotary drilling rig

When would a pile splice be necessary?

• When the pile shoe is damaged

• When the pile needs to be extracted

• When the pile needs additional lateral support

• When the pile length is insufficient to reach the required depth

Which type of pile typically requires the removal of soil during installation?

• Spun pile

• Driven steel pile

• Rotary bored pile

• Precast concrete pile

What is the main advantage of using a replacement pile over a displacement pile?

• Faster installation time

• Greater soil displacement for lateral support

• Easier to splice during construction

• Less noise and vibration during installation
