| Description |
This was a Joint Industry Project
(JIP) to evaluate methods to predict the capacity of drilled and grouted (D&G) piles.
The use of underwater hammers in deep water is expensive and it may not be possible in
water depths greater than 2,000 feet. This makes a driven pile foundation unattractive or
not feasible. An alternative is to use drilled and grouted piles which can be placed by a
drill ship. One problem associated with D&G piles is that their capacity can not be
checked as easily as that of driven piles where the pile driving record is an indicator of
pile capacity. The purpose of this project is to initiate the development of a method for
evaluating the tension capacity of D&G piles. |
