THE AREA OF RATIONAL USE OF BRIDGES OF VARIOUS TYPES FOR HIGH-SPEED HIGHWAYS

Based on the analysis of the rational use of bridge structures of various types for high-speed railways, the dependences of the parameters of artificial structures, both in climatic and regional conditions, were obtained. The types of reinforced concrete bridge structures, their technical parameters and corresponding characteristics with an increase in speed due to an increase in dynamic loads are considered. For reasons of construction technology, as well as maintenance, the use of a through method for the construction of ballast less tracks from a free site along the bridge was revealed, without changing the method of construction.
