An Investigation of High Speed Transport Systems: Design and Geodynamics

Abstract

High speed rail systems are an important transportation system that is desired to be developedin almost every country around the world. These systems made train transportation moreattractive than conventional railways. Train speed is the most effective parameter that differsfrom each other when compared to traditional railways. This difference requires special designs in order to keep the vibration that will occur during movement in high speed systemswithin the limits that will not harm the substrate and the environment. Vibrations caused byhigh train speed are transferred from the rails to the sleeper and to the ballast system throughthe sleeper in common ballast systems, and can cause serious deformations in the rail systemand the ground. These cases that pose a problematic in high speed rail systems need to be resolved. The geodynamics of these systems examine the vibration problems caused by motioncaused by high-speed trains and the deformations caused by this vibration. It tries to ensurethe conformity of the rail system to the continuous movement and the safety conditions of thesystem. The design of high-speed rail systems, which have many variables and unknowns compared to traditional railways, is the common work area of ground and railway engineering. Inthis article, the geodynamics of fast transportation systems, the main structures and design ofthese systems, and their operation methods are examined. At the same time, the ballasted andnon-ballasted conditions of fast transport structures are also discussed in detail.
