Yan, S.; Jia, Z.; Liu, W., and Zhang, X., 2015. Case history: Large diameter and supper long pile-running under self-weight in Liwan Oil Field.

The pile-running frequently occurs because of the great weights of both the pile and the hammer. Thepile-running mechanism is super long and large-diameter piles are commonly used for constructing ocean platform foundations. Pile-running discussed in the current study through case analyses. A predicting procedure is developed based on the limit equilibrium of pile weight and soil resistance. Reduction factors for soil strength used to calculate the skin friction are also suggested in the current study. The Berezantsev approach is recommended for calculating the end bearing resistance to the running pile, which can improve the precision of the estimation compared with that of commonly used methods. The suggested method is used to predict the pile-running case in a practical project, and the calculated results are consistent with the driving records.
