• Abstract:
  In Florida, many structures are built on driven piles. Though it seems straightforward, pile ; driving involves complex interactions between the pile, the hammer, the soil, and driving ; procedures. Soils can even rebound, or push back, after each hammer blow. Some rebound is ; expected, but when it is beyond certain limits, it is referred to as high pile rebound (HPR). Piles ; designed for new construction in areas of the state that have historically encountered HPR ; require additional hammer blows to drive the pile ; to the desired depth. These additional blows risk ; damage to the pile and a loss of supportive capacity. ; Predicting HPR requires a better understanding of the ; engineering properties of various Florida soils. ; Florida Institute of Technology researchers conducted ; a testing program to help engineers determine typical ; properties of soils encountered during pile installation ; when HPR occurs.
