Abstract
The objective of the study was to record and evaluate ground vibration and noise generated during the installation of rammed aggregate piers (RAPs). Summarized are ground vibration and noise induced by the ramming equipment (i.e. the hydraulic break hammer and rammer) during the installation of forty-five RAPs at a single site. Data were collected during the entire installation process for each pier, which allowed for the measurement of ground vibration and noise levels for periods when the ramming equipment was positioned at different depths within the RAP. Measurements were also taken at different horizontal distances from the ramming equipment and RAP being installed. The entire data set consists of over 160 ground vibration measurements and over 260 noise measurements. Peak ground velocities measured during the study ranged between approximately 0.5 and 15 millimeters per second for horizontal distances ranging between 1.5 and 10.5 meters. Corresponding vibration frequencies ranged between approximately 20 and 60 Hz. Measured noise levels ranged between approximately 82 and 111 dBA for measurement locations between approximately 1.5 and 10.5 meters from the hammer. Overall, these measured ground vibrations and noise levels are moderate in nature and below those typically generated during pile driving.
