What is the primary function of a deep foundation?
To distribute loads over a wide area at shallow depth
To transfer building loads to stronger soil or rock layers at greater depths
To reduce the cost of the superstructure
To improve the architectural appearance of the building
Which type of deep foundation is prefabricated and driven into the ground using a hammer?
Bored Piles
Diaphragm Walls
Driven Piles
Pier Foundations
A foundation that transfers loads primarily through the friction between its surface and the surrounding soil is called a/an:
End-Bearing Pile
Combined Pile
Friction Pile
Shallow Foundation
Which deep foundation type is constructed by drilling a hole, placing reinforcement, and filling it with concrete?
Driven Piles
Basement Foundations
Bored Piles
Raft Foundations
What is a common advantage of bored piles over driven piles?
Higher installation noise and vibration
Suitability for sites with low headroom or vibration restrictions
Faster installation in all soil conditions
Lower quality control requirements
Which foundation type is typically used for heavy bridge piers and tall structures where large diameters are needed?
Pad Footings
Pier Foundations (Caissons)
Strip Foundations
Raft Foundations
What is used to prevent a bored pile hole from collapsing during excavation?
Quick-setting concrete
Temporary casing or bentonite slurry
Wooden planks
Reinforcement cages
Deep foundations are generally required when:
The surface soil is strong and stable
The water table is very low
The surface soil is weak or compressible
The building has only one story
