Abstract

The vibratory characteristics of vibro-driven piles into the ground have not so far been discussed systematically in detail. This paper concerns the results of monitoring vibro-driven piles in various types of ground. In order to assess the monitoring of vibration performance, time-series monitoring data on the reaction force at the pile tip and the vibratory acceleration of the pile top are analyzed in relation with the soil profiles of four monitoring sites. As the result, it has been elucidated that the pile tip reaction force and vibratory acceleration are systematically presented by the dynamic force and the mass weight of the vibrohammer and pile. Furthermore, engineering applications of the vibratory characteristics of vibro-driven piles are presented.

Case Histories and Vibratory Characteristics of Vibro-driven Piles

St. Louis, Missouri

The vibratory characteristics of vibro-driven piles into the ground have not so far been discussed systematically in detail. This paper concerns the results of monitoring vibro-driven piles in various types of ground. In order to assess the monitoring of vibration performance, time-series monitoring data on the reaction force at the pile tip and the vibratory acceleration of the pile top are analyzed in relation with the soil profiles of four monitoring sites. As the result, it has been elucidated that the pile tip reaction force and vibratory acceleration are systematically presented by the dynamic force and the mass weight of the vibrohammer and pile. Furthermore, engineering applications of the vibratory characteristics of vibro-driven piles are presented.
