Abstract
For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version).ABSTRACT In the article the questions connected with the choice of rational parameters of the vibration protection structures of the metro t rack superstructure are considered. Results of an assessment of ways to increase the efficiency of vibroprotective properties of blocks LVT-M are given. Proposals are made to improve the methodology for such an assessment, which should take into greater account the deformation characteristics of the track, the structural features of the tunnel and other structures in the metro zone. Particular emphasis is placed on the importance of using materials which dynamic stiffness is slightly higher than the static in the range of the studied frequencies of 2-63 Hz. Keywords: vibration protection, track superstructure, metro, track stiffness, vibration isolation efficiency.
