Assessment of the impact of pile driving on an existing residential building by measuring the vibration effects

The paper presents the results of vibromonitoring, the purpose of which was to determine the vibration parameters on the existing residential building from pile driving. Pile driving was assumed in conditions of dense urban development, near the building. The main evaluation parameters of vibration were: vibration displacement (amplitude), vibration velocity, frequency, and vibration acceleration. Vibration parameters were measured at different distances from the excitation source: in the vicinity of the pile, at a distance of 5, 15, 40 m, and near the building. According to the results of the measurements, the relationships of the vibroparameters changes by the driving time were obtained, based on the analysis of which the dependence of the vibroparameters changes depending on the distance from the excitation source was determined. Also, the paper presents statistical data of the obtained results, based on which the analysis of the relationship of the obtained particular values of vibration indicators was carried out. In the conclusion the calculation of the permissible distance of pile driving, made based on the vibration attenuation coefficient, determined by the results of actual measurements, is presented.
