Piles fail lateral load test
Piles fail lateral load test
(OP)
Hello all,
I have a project with 30' deep piles currently in construction. The contractor has driven test piles and is testing them for lateral load capacity in accordance with ASTM D3966. He has indicated that the piles are failing the required capacity miserably. I am having him test another pile, but if the results are similar, what can be done? By the way, the lateral load capacity was determined by the geotechnical engineer during design.

Drive more piles
Drive wider piles
Add battered piles
Improve the soil around the upper section of the piles
Use the pile cap to resist lateral movement

I would wonder if the encountered soils/rock are as expected.

A fixed head pile cap would help.
The geotechnical engineer should be in a position to provide more insight, providing that the "geotechnical engineer" is really a geotechnical engineer.

Then if you need the 40 tons service level and IF the piles are more or less floating it seems a difficul issue, even inclined piles would have some difficulty (but would help) and if not compliant you would have to use very rigid pile/caisson outfits to deeper layer of fixity, an unlikely proposition, hence more inclined piles.
If point bearing, inclined piles as suggested may ber reasonable solution if acceptable from seismic behaviour.

Just noticed the last post was 5 May - wonder what happened ....
