A deep foundation is crucial in large-scale construction projects such as skyscrapers, bridges, and industrial facilities. It is a type of foundation that transfers building loads deeper into the earth, beyond the surface layer, unlike a shallow foundation. This is achieved by installing vertical structural elements, known as piles, which are driven or drilled deep into the ground at the building site.
There are several reasons why a geotechnical engineer would recommend a deep foundation over a shallow foundation. One of the most common reasons is the need to support large design loads. Shallow foundations are unsuitable for transferring heavy loads to the earth, and the structure’s weight could cause it to sink or shift over time. Deep foundations can be designed to transfer loads to stronger and more stable soil layers, providing a secure and sturdy foundation for the building.
Another reason for using a deep foundation is when there is poor soil at shallow depths. Soft soils such as clay, sand, or silt are unsuitable for shallow foundations as they can compress or settle over time, causing the structure to sink or shift. Deep foundations can be installed in deeper, more stable soils, providing a secure and stable foundation for the building.
Site constraints can also factor in choosing a deep foundation over a shallow one. Deep foundations can be installed with minimal disturbance to the surrounding area, allowing construction to proceed even in tight spaces.
Different types of deep foundations, including piles, piers, drilled shafts, and caissons, each with unique advantages depending on the project requirements. Piles are generally driven into the ground in situ, while other deep foundations are typically put in place using excavation and drilling. The naming conventions may vary between engineering disciplines and firms.
Deep foundations can be made from various materials such as timber, steel, reinforced concrete, or prestressed concrete. The choice of material depends on several factors, including soil conditions, environmental factors, and load capacity.
