Abstract
The vibration characteristics of penetration piles into the ground has not been discussed systematically in detail so far. As for the vibration performance of penetration piles into the ground, it has been elucidated that the vibrating motion of reaction force of pile tip can be classified into five categories. In this paper, in order to estimate the peak value of the classified vibrating motion, monitoring of vibration performance-reaction force of pile tip and acceleration of pile top-was carried out in sandy grounds, by means of the reaction force meter and acceleration meter attached at around the tip and the top of casing pile for the installation of sand compaction pile. Based on the monitoring data, it was elucidated that reaction force, acceleration and penetration time were systematically represented by dynamic force and mass weight of vibrator and piles. Furthermore, engineering application of the vibration characteristics of the penetration piles was presented.
