This paper presents results obtained with the use of accelerometers during in-situ testing and its comparing with results from numerical simulations. Horizontal accelerations of propagating impulses caused by driving the prefabricated piles were recorded. Range of the quakes as well as amplitudes of longitudinal and transverse horizontal accelerations of propagating vibrations on the terrain surface were determined. The recorded results were used to calibrate the numerical model of the finite element method. The most important factor influencing the propagation of impacts is the phenomenon of damping of the propagating wave in the soil. The mechanism of damping proposed by Rayleigh was used in the analysis, which, when selecting the appropriate parameters of the model, is able to realistically simulate the observed phenomena. The soil, in which the propagation of impulses occurred, was described with the use of linear-elastic model. Modulus of deformation correspond to the values of small deformations, which occur during the wave propagation in the subsoil. The impulse giving vibrations was caused by the falling hammer on the driven pile. The axial symmetry of the border condition was used in the analyses. The results of numerical simulations were compared with the results of field measurements of accelerations at different distances from the source of vibration. A good consistency of acceleration amplitudes in the direction of vibration propagation was achieved and it depended on the distance from location of the driven pile. The obtained results will be used in the future to assess the extent of the impacts on the environment and values of acceleration on elements located in the vicinity of the structure.

Vibratory driving is the most efficient method of sheet pile installation. The elimination or at least reduction of harmful consequences of sheet pile vibratory driving becomes an increasingly important and often the decisive factor in the selection of the excavation protection technology. In difficult soil conditions with strength soil parameters, pressure water jetting precedes sheet pile driving. This technique changes the soil properties, destroying its existing structure near the installed sheet pile. Unfortunately, the results and achievements of contractors using this technique are very often held confidential or simply remain in the records and it is difficult to find papers on this subject. This article features a detailed description of jet-assisted sheet pile driving, including a prefabrication description for the sheet pile toe used to jet water through, water pressure and quantity data and the results with regard to reduce vibrations and noise, as well as to the increase in sheet pile vibratory driving performance.
