Piles of bridge built in 1972 in Vietnam follow american standard

[LeuBong]

This is Binh Trieu bridge built in 1972 in Saigon - Vietnam (37 ft wide). It was supposed to be applied AASHO standanrd. But its foundation piles is still mysterious (diameter of pile at main span is 58 inches).

Could someone tell me which type of piles (name of pile, typical drawing, etc. ) and tell me are there similar type of bridges in the US.

Many thanks in advance.

Saigon is sitting on super deep mud right? My understanding is the city has some very challenging geotechnical conditions, so I’m guessing the piles were designed for the specific conditions at the site and available local construction materials and capabilities at the time. I don’t think there will be any drawings you could point to and definitively say this bridge was built with the same pile design.

Possibly precast concrete tubes bored into the base. Picture is from the Chesapeak-Bay-Bridge-Tunnel, Virginia Beach VA. Base geology here is complicated, as the structure crosses the chesapeak bolid hole
