ANALYSIS OF THE VIBRATION IMPACT ON THE SOILS OF VASILYEVSKY ISLAND OF ST. PETERSBURG

The development of St. Petersburg is accompanied by an increase in dynamic loads. For example, in 2016, the opening of the central section of the Western High-Speed Diameter highway is planned to open. Moreover it is planned to open the Mining Institute, Gavan and Marine Facade metro stations in this area. The question about the prediction of the dynamic instability of the soils needs further investigations, as it requires not only an accurate assessment of the loads, but also reliable modeling of changing the physical and mechanical properties of the soils. In 2015 for the first time the state standard "Methods of laboratory determination of dynamic properties of dispersed soils" was introduced only in Russia. At the same time, the document does not regulate the choice of test schemes and modes for a specific type of soil, and there are no recommendations in the existing construction rules on the application of the obtained results of soil tests. In this paper, qualitative and quantitative analyzes of the properties of the vibrational field on the territory of Vasilievsky Island of St. Petersburg were done. Considered sources of vibration. Analyzed characteristics of the sources, such as:metro, trams, automobiles.
