Deep foundation

Deep Foundation

A deep foundation is a type of foundation that is used to transfer the load of a structure to deeper layers of soil or rock, when the shallow soil is unable to support the structure's weight. It is commonly used in the construction of tall buildings, bridges, and other large structures.

Types of Deep Foundations

There are several types of deep foundations, each designed to suit different soil and site conditions. Some of the most commonly used types include:

1. Pile Foundations: Pile foundations are vertical structural elements that are driven into the ground. They transfer the load of the structure through skin friction and/or end bearing. Piles can be made of various materials such as concrete, steel, or timber.

2. Caissons: Caissons are large watertight structures that are sunk into the ground to form a foundation. They are commonly used in the construction of bridges and other structures that require a strong foundation in waterlogged areas.

3. Drilled Shafts: Drilled shafts, also known as drilled piers or bored piles, are deep foundation elements that are created by drilling a hole into the ground and then filling it with concrete or other suitable materials. They are often used in areas with difficult soil conditions.

4. Micropiles: Micropiles are small-diameter piles that are typically used in areas with limited access or low headroom. They are often used to support structures in urban areas or in retrofitting existing structures.

Advantages of Deep Foundations

Deep foundations offer several advantages over shallow foundations in certain situations:

1. Load Capacity: Deep foundations can support much larger loads compared to shallow foundations, making them suitable for tall buildings and heavy structures.

2. Soil Conditions: Deep foundations can be designed to accommodate various soil conditions, including weak or expansive soils, which may not be suitable for shallow foundations.

3. Settlement Control: Deep foundations can help control settlement by transferring the load to deeper, more stable layers of soil or rock.

4. Flexibility: Deep foundations can be designed to accommodate various site constraints, such as limited space or difficult access.
