Title: | Global vibration intensity assessment based on vibration source localization on construction sites : application to vibratory sheet piling | Authors: | Wang, S Zhu, S |
Issue Date: | Feb-2022 | Source: | Applied sciences, Feb. 2022, v. 12, no. 4, 1946 | Abstract: | Various construction activities (such as piling) often generate high-intensity ground vibrations that adversely affect the surrounding environment. A common way of assessing vibration impact is to conduct on-site ground vibration monitoring at several selected locations. However, as vibration sources are often not pinpointed in the construction process, this approach cannot predict the vibration intensities at locations other than those monitored points. Therefore, the localization of vibration sources (e.g., vibratory sheet pile driving location) is crucial to quantify the correspond-ing vibration intensities in a broad area. This paper investigates a time-based source localization method based on wave propagation characteristics derived via three-dimensional finite element modeling of vibratory sheet pile driving in an infinite half-space soil domain. Satisfactory accuracy in the localization of the vibratory driving sources was achieved in all investigated numerical ex-amples. Field validation tests were also conducted on a construction site with ongoing vibratory sheet pile driving work. A site-specific empirical formula was adopted to model the attenuation of measured vibration intensities with the increasing distance from the localized vibration source. As such, the combined utilization of the estimated vibration source location and the adopted empirical formula can achieve vibration intensity assessment in a broad surrounding area rather than being confined to a few monitored points. | Keywords: | Construction-induced vibrations Global vibration intensity estimation Spatial wave propagation Three-dimensional finite element modeling Time-based source localization method |
