Synthesis of Information Related to Highway Problems. Topic 45-05. Design and Load Testing of Large Diameter Driven Pipe Piles

Open-end cylinder pipe piles are a type of deep foundation commonly used for the support of bridge abutments. As the need to support larger lateral, seismic, and axial loads increases, users are moving towards large diameter cylinder piles (Rausche & Webster 2007, Transportation Research Board (TRB) 2004). Large diameter cylinder piles are an alternative to similar-sized drilled shaft foundations or pile groups. They are suited to a variety of applications, most commonly in earthquake prone regions and over waterways where ship impact and lateral loads are a concern. The design and load testing of driven pipe piles is strongly influenced by the diameter and thickness of the pile. Common design methods to determine the load carrying capacity of a large diameter open-end cylinder pile are based on solid and small diameter pipe piles for skin friction and end bearing, respectively (McVay 2004). These design methods do not account for the differences in soil-pile-hammer interaction between small and large diameter driven piles. Issues include the degree of soil plugging or internal skin friction that exists, non-linear vibration effects and scalability concerns. Furthermore, significant questions have been raised regarding capacities determined by dynamic means, often requiring static tests to verify capacity (TRB 2004). A study of current practices for the design, testing, and use of large diameter driven pipe piles in highway applications is needed as transportation agencies begin to calibrate resistance factors for this type of deep foundation system. The project objectives are: (1) To locate and assemble documented information on the design, installation, and testing of large diameter cylinder piles; (2) To learn what practice has been used for estimating and verifying capacity of large diameter open end piles; (3) To identify all ongoing research; (4) To learn what problems remain largely unsolved; and (5) To organize, evaluate, and document the useful information that is acquired. Information will be gathered through a literature review and a survey of State Departments of Transportation (DOTs).
