Experience with the vibration monitoring method for driving piles in an existing foundation

The article presents the results of vibration monitoring, the purpose of which was to determine the vibration parameters of an existing industrial building from pile driving. Ground vibrations induced by pile driving are transmitted through the subsurface via elastic wave propagation mechanisms and may remain perceptible at significant offsets, frequently exceeding a few hundred meters from the source. The main evaluation parameters of vibration: vibration displacement (amplitude), vibration speed, frequency and vibration acceleration. Vibration parameters were measured at different distances from the excitation source: near the pile, at a distance of 10, 50, 100 m. According to the results of the measurements, the dependence of the vibration parameter changes on the time of hammering based on the analysis of which the dependence of the vibration parameter changes depending on the distance from the excitation source was determined. The work also presents statistical data of the obtained results, on the basis of which an analysis of the relationship of the received individual values of the vibration indicators was carried out.
