    Study Notes

    Foundation Classifications

    • Deep foundations are classified as those with a depth range of more than 10-15 meters.
    • Shallow foundations are classified as those with a depth range of less than 10-15 meters.

    Foundation Types

    • Shallow foundations are typically used for small to medium-sized structures, such as houses and garages.
    • Deep foundations are typically used for structures that are located on unstable soils.

    Installation Methods

    • Mat foundations are installed by pouring concrete to create a large, flat slab that supports the entire structure.
    • Driven piles are installed by driving a long, slender column into the ground to transfer loads to deeper, more stable soil.
    • Helical piles are installed by screwing a column into the ground to provide lateral and axial support.
    • Micropiles are installed by drilling a small diameter hole and filling it with concrete to create a mini-pile.

    Purpose of Foundations

    • The purpose of a slab-on-grade foundation is to provide a level surface for the structure to be built on.
    • The purpose of a strip footing is to distribute the weight of the structure evenly across the soil.
    • The purpose of a caisson is to provide a watertight chamber for construction activities.
    • The purpose of an auger cast pile is to provide a deep foundation system that can transfer loads to deeper, more stable soil.
    • The purpose of micropiles is to provide additional support to existing structures or to stabilize soil.
    • The purpose of spread footing is to distribute the weight of the structure evenly across the soil.

    Soil Conditions

    • Deep foundations are typically used in soil that is unstable or has low bearing capacity.
    • Shallow foundations are typically used in soil that is stable and has high bearing capacity.
