Retaining Wall Structures

What is the main function of a retaining wall?

• Diverting water

• Retaining soil or materials

• Supporting structural loads

• Enhancing landscaping aesthetics

Which of the following is critical to ensuring the stability of a retaining wall?

• Proximity to adjacent structures

• The appearance of the wall

• Number of workers on-site

• Soil type, wall height, and applied loads

Which of these is NOT typically considered during retaining wall design?

• Hydrostatic pressure

• Surcharge loads

• Soil temperature

• Earth pressure

How does the soil’s angle of internal friction primarily affect retaining walls?

• By influencing the soil pressure

• By determining the wall height

• By selecting construction equipment

• By altering the wall’s external design

What is the main purpose of providing drainage behind retaining walls?

• Strengthening wall materials

• Preventing soil compaction

• Improving soil quality

• Reducing water pressure

How does a gravity retaining wall resist lateral soil pressure?

• Using soil nails

• By being anchored

• Through its weight

• With reinforcement bars

Cantilever retaining walls are commonly constructed from:

• Wood

• Reinforced concrete

• Brickwork

• Stone masonry

Which wall type consists of wire mesh filled with rocks?

• Crib wall

• Gravity wall

• MSE wall

• Gabion wall

A crib retaining wall is recognized by its:

• Frames of timber or concrete filled with stones or soil

• Heavy reliance on deep anchors

• Precast concrete panels

• Interwoven steel mesh with rocks

What reinforces a mechanically stabilized earth (MSE) wall?

• Concrete blocks layered vertically

• Metallic strips or geogrids in the backfill

• Reinforced steel plates

• Timber ties in the foundation
