Shallow and deep foundations characteristics and types.
Understand the Problem
The text provides definitions and characteristics of shallow and deep foundations in civil engineering, explaining their suitability based on various conditions related to soil properties, load capacity, and construction requirements.
Answer
Shallow: strip footings, isolated footings, combined footings, mat foundations, grade beams. Deep: pile caps, piles, drilled piers, caissons.
Shallow foundations include strip footings, isolated footings, combined footings, mat foundations, and grade beams. Deep foundations include pile caps, piles, drilled piers, and caissons.
Answer for screen readers
Shallow foundations include strip footings, isolated footings, combined footings, mat foundations, and grade beams. Deep foundations include pile caps, piles, drilled piers, and caissons.
More Information
Shallow foundations are typically used when the load of the structure is light relative to the strength of the surface soils and are more cost-effective up to 3 meters deep. Deep foundations are used to anchor structures into deeper, more stable soil or rock layers, often exceeding depths of 3 meters, and are generally more expensive.
Tips
Common mistakes include not considering the load-bearing capacity of the soil, leading to inadequate foundation depth.
