Timber piling axial capacity
Timber piling axial capacity
(OP)
Question regarding axial capacity of altered driven timber piling. The 35-foot long, 10-inch diameter piling was driven 25 feet into a submerged sandy bottom. Realizing it was driven too deep, the contractor pulled the pile up 5 feet. Question: What is the effect on the axial capacity of the piling compared to if it had originally been driven 20 feet as specified?





RE: Timber piling axial capacity
You need to get new pile capacity curves from your geotech. I expect that your new curves will only include skin friction and no tip capcity. In sandy soil, you may have virtually no capacity unless you are also driving through a good clay.
Good luck- I fear that you will need it.
