Driven concrete filled pipe piles
Driven concrete filled pipe piles
(OP)
I am working on the construction of a boat house in lake
The edge of the boat house is 25 ft away from the edge of water. The max depth of water is 5 ft
The structural has recommended the construction of driven closed ended pipe piles with a diameter ranging from 6 in to 12 in, to be filled with concrete.
Can someone please provide me with a link or a reference, a design example or manual or text dealing with the above subject.
Thank you

If you're looking for something more specific to your situation (piles driven in a lake), I can't help you.

What has the geotechnical engineer recommended?!

I believe that the pipe piles will be closed end while driving into the ground and will be later filled with concrete ( which I believe will greatly increase the tip capacity).

If you go to this site you can probably find a manual on what you're dealing with to download. I think I even saw some free public domain software on the site. I'm one of the authors on the Manual for Design and Construction Monitoring of Soil Nail Walls

Deep foundations can get very complicated. Different types of piers also have different methods and different ultimate bearing capacities.
I would personally recommend using Meyerhof's method for calculating Qp (assuming a firm strata exists) as his method is a good 'middle of the road' or average approach and is generally conservative.
However, for estimating Qp for construction purposes (needed to overcome for driving), I would recommend using Vesic's Method - based on the theory of expansion of cavities. It is generally considered to be more accurate (though not as conservative).
Though if no firm strata exists, then it is likely that Qtip will only contribute <20% of the ultimate resistance as most will be derived from skin friction.
