Abstract

The article deals with the issues of ensuring seismic stability of high-speed railway overpasses, taking into account the experience of their design and construction in developed foreign countries. The review of technical solutions for ensuring earthquake resistance of overpasses and bridges located on high- speed and high- speed railway lines in the world and in the Republic of Uzbekistan is carried out. The method of selecting the optimal parameters of earthquake-proof bearing parts of bridges and overpasses on high-speed railway lines is presented. The article proposed a new solution of dynamic oscillation damping of the bridges, wherein the dampening mass (superstructure) is located between the two protected objects (supports) and dampens their oscillation. Thanks to this approach, several times reduces the seismic load on the supports of the girder bridges in high-speed lines.
