Abstract

Vibrations generated by driven pile installation often affect adjacent and surrounding buildings in tightly spaced urban environments. These vibrations can lead to complaints from neighboring residents and businesses and/or cause structural damage to adjacent structures, especially older and historic buildings. Pile driving vibrations are of particular interest in the Charleston, South Carolina area since the majority of new structures are founded on driven pile foundations bearing within the underlying Cooper Marl Formation. By knowing the vibration attenuation relationship of a project area (i.e. the decrease in vibration amplitude with distance), it is possible to develop pile installation plans that minimize discomfort to residents and the risk of damage to adjacent structures. In addition, knowledge of the vibration attenuation relationship for a site can assist in determining the limits for pre-condition surveys to document the existing conditions of adjacent structures prior to pile driving operations. This paper presents the case histories of vibrations monitored during seven driven pile and one vibratory pile construction projects in the Charleston, South Carolina area. The vibration data was then analyzed to evaluate the energy-attenuation relationships for the individual sites. Comparisons of these analyses were then made in an effort to determine typical energy-attenuation relationships for driven piles within the Charleston, SC area.

Pile Driving Vibration Energy-Attenuation Relationships in the Charleston, South Carolina Area

New York, New York

Vibrations generated by driven pile installation often affect adjacent and surrounding buildings in tightly spaced urban environments.
