A deep foundation installation for a bridge in Napa, California, United States. Pile driving operations in the Port of Tampa, Florida. A deep foundation is a type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a
Screw piles were first described by the Irish civil engineer Alexander Mitchell in a paper in Civil Engineer and Architect's Journal in 1848; however, helical piles had been used for almost a decade by this point. [2] Screw foundations first appeared in the 1800s as pile foundations for lighthouses, [3] and were extensively used for piers in ...

These sensors are connected to an instrument (such as a pile driving analyzer), that records, processes and displays data and results. As long as the wave travels in one direction, force and velocity are proportional and related by the expression F = Zv, where: Z = EA/c is the pile impedance; E is the pile material modulus of elasticity
Franki piles can be used as high-capacity deep foundation elements without the necessity of excavation or dewatering. [4] They are useful in conditions where a sufficient bearing soil can only be reached deeper in the ground, [5] [6] and are best suited to granular soil where bearing is primarily achieved from the densification of the soil around the base.

A grade beam or grade beam footing is a component of a building's foundation. It consists of a reinforced concrete beam that transmits the load from a bearing wall into spaced foundations such as pile caps or caissons. [1] It is used in conditions where the surface soil's load-bearing capacity is less than the anticipated design loads.
Timber-pile bridge with steel stringers, New Jersey. Timber pilings serve as the foundations of many historic structures such as canneries, wharves, and shore buildings. The old pilings present challenging problems during restoration as they age and are destroyed by organisms and decay. Replacing the foundation entirely is possible but expensive.
The soil response for each pile segment is modeled as viscoelastic-plastic. The method was first developed in the 1950s by E.A. Smith of the Raymond Pile Driving Company. Wave equation analysis of piles has seen many improvements since the 1950s such as including a thermodynamic diesel hammer model and residual stress. Commercial software ...
