Jul 1, 2016 · This document presents information on the analysis, design, and construction of driven pile foundations for highway structures. This document updates and replaces FHWA NHI-05-042 and FHWA NHI-05-043 as the primary FHWA guidance and reference document on driven pile foundations.
Driven piles, also known as displacement piles, are a commonly-used form of building foundation that provide support for structures, transfering their load to layers of soil or rock that have sufficient bearing capacity and suitable settlement characteristics.
Driven piles. Driven (or displacement) piles are driven, jacked, vibrated or screwed into the ground, displacing the material around the pile shaft outwards and downwards instead of removing it. Driven piles are useful in offshore applications, are stable in soft squeezing soils and can densify loose soil. There are two groups of driven piles:
Driven precast concrete piles are constructed by hammering the piles into the soil to a depth greater than 40m by an adjustable hydraulic or diesel hammer. Driven precast concrete piles are widely used because of their versatility and suitability for most ground conditions.
Mar 8, 2016 · A "driven pile foundation" is a specific type of pile foundation where structural elements are driven into the ground using a large hammer. They are commonly constructed of timber, precast prestressed concrete (PPC), and steel (H-sections and pipes).
construction of timber pile foundations. The organization of the manual is presented below. Chapter 2 provides an overview of the design and construction process for a timber pile foundation. Chapter 3 covers the selection of the strength properties of timber piles and considerations with respect to pile durability.
Driven Pile Foundations. This document presents the design methods and communication steps between Structure Design (SD) and Geotechnical Services (GS) for the load and resistance factor design (LRFD) of driven pile foundations used for support of bridges, retaining walls, non-standard walls, signs, and other structures.
