Pile Heave and Redriving

Upward pile movement or pile heave commonly occurs whenever large numbers of closely spaced piles are driven. Pile heave is generally attributed to displacement of the foundation soils during subsequent driving of adjacent piles. The majority of engineers appear to be of the opinion that all heaved piles must be redriven. Very few documented case histories dealing with this problem are available in the engineering literature. This paper presents detailed field data with analyses pertaining to pile-heave problems that developed during construction of end-bearing pile foundations for a large industrial pant. Two individual areas within the plantsite are selected for detailed study.
