ESSENTIAL REQUIREMENTS FOR ROADBED DESIGN OF HIGHSPEED RAIL LINES

Objective: Scientific justification of requirements to roadbed design of high-speed networks (HSN) for the purpose of constructing “Moscow–Kazan–Yekaterinburg” railroad line, as well as implementation of “Eurasia” and “Yekaterinburg–Chelyabinsk” HSN projects. Methods: The analysis of modern roadbed design standards for HSN was carried out. The justification of HSN roadbed norms and requirements involved system analysis of HSN engineering and construction in Western Europe, China, Japan and other countries with well-developed high-speed network. Results: The fundamental principles and requirements, which are to be taken as a basis of HSN roadbed engineering, were determined. Practical importance: The obtained results are to be used in HSN roadbed engineering and construction, performed on the territory of the Russian Federation.
