Marine Pile Lateral Resistance
Marine Pile Lateral Resistance
(OP)
I am in the process of designing an inland (freshwater) marina on a lake in a 110 MPH wind zone. I am having some trouble locating information relating to the lateral force resistance of vibrated-in wood piles. The piles are 8"-10" in diameter, will be vibrated to a refusal depth approximately 10' below the lake bottom, and will reside in approximately 8' of water. I need a way of calculating the lateral resistance of the pile based on some assumed soil parameters. I have found some great resources at www.vulcanhammer.net to calculate the forces resulting from wind on vessels, but nothing on the piling's capabilities. Anybody have any insight on this? Thanks!

As the issue is vast maybe some hints would help those reading to give good advice, particularly the general setup and the kind of soil, for that will place the case in one of the types in the books or programs.

Will try to find something more specific.

Were it right anything therein it would be more than anything wood pile properties what to state.
RE: Marine Pile Lateral Resistance
Of all foundation types, only deeply embedded wooden or prestressed concrete piles at least 9 inches in
diameter-wooden or concrete-invariably performed well in the face of Hugo's waves and surge. Failures
were mainly due to rot, or to over-notching of the pile for the floor beam (Interagency Hazard Mitigation
Team 1989; Miller 1990; Richardson 1990; Rogers 1990a; Rogers and Sparks 1990; Wang 1990).
Wooden piles, 10 inches or more in diameter, driven or jetted 10-15 feet into the ground were most effective
during Hugo (URS Consultants 1991a).
The Hugo experience suggested that the lateral strength of wood piles and/or the lateral soil resistance of all
types of piles in sandy soils has been significantly underestimated. Those foundations appeared to consistently
survive water, wave, and erosion conditions under which damage would have been expected (Rogers 1990a).
