THE IMPACT OF HIGH-SPEED ROLLING STOCK ON THE SUPERSTRUCTURE AND THE DESIGN OF IMMERSED TUNNELS
Abstract
In connection with the strategic importance of the development of high-speed traffic in Russia, it is necessary to thoroughly study the problem of the impact of high-speed rolling stock on the superstructure and artificial structures. The article deals with the impact of high-speed rolling load on beams for the purpose of determining the impact of high-speed rolling stock on the superstructure of the track and design of immersed tunnels. Using the Green's function, the Fourier transform, and the theory of residues, we determine the general form of the dependence of the deflections in the beam on the velocity of the load. An example of the determination of a stress-strain state and critical speed for a beam with use of the regularities obtained in the course of the study is considered. It was revealed that when the railway track is located on soft soils, taking into account the current level of technical development, it is possible to achieve critical speeds. The effects of increasing the vibrations, manifested when the rolling stock reaches critical speeds, can be dangerous and require detailed study.
