Abstract: The aim of the study is to assess the dynamic effects of pile driving on adjacent buildings and structures. The article presents the results of studies research of determination pile driving vibration velocity of foundations located next to the job site of buildings with inn-process equipment at the mining and processing plant. On the site there are two thickeners, motor room building with equipment, and transformer substation with three transformers. Vibration velocity measurements were carried out by a special technique. The vibration analyzer sensor was installed at the points located on the surfaces of the base plates of steel supports of thickeners, columns of the motor room and on the embedded parts of the transformer substation. Vibration velocity registered on the foundations of buildings and construction structures of the slurry pump did not exceed the limit value. The vibration velocity of the girder foundation of the transformer substation was much lower than the limit value velocity for the brick building. Impact effects did not lead to a breakdown of the technological process on the studied objects. Bearing and enclosing structures of buildings and structures were not damaged.

Key words: consequence assessment, vibrational speed, pile driving, buildings, constructions.
