This paper considers the collision of hammer to pile driven into two layers of foundation base. The pile side friction in each layer is different, pile bottom is subjected to constant resistance. This paper uses the D'alembert wave propagation method and longitudinal collision theory of elastic bars to determine the compressive force of the buffering on the pile; thus, it will be easy to drive piles safely and effectively.

摘要

This paper considers the collision of hammer to pile driven into two layers of foundation base. The pile side friction in each layer is different, pile bottom is subjected to constant resistance. This paper uses the D'alembert wave propagation method and longitudinal collision theory of elastic bars to determine the compressive force of the buffering on the pile; thus, it will be easy to drive piles safely and effectively.
