Prediction of ground vibrations around the turnout system induced by the tilting train

초록

In Korea, it has been planned to apply high speed tilting train, which operates at the maximum speed of 200km/h, to conventional lines by the year of 2010. However, for the application of the tilting train to conventional lines, it is prerequisite to establish a stable turnout system allowing the tilting train to pass through it without reducing speed. Therefore, the improved turnout system for the speed-up of conventional lines has been developed and the prototype of the turnout system has been constructed. However, levels of impact-induced ground vibrations from the discontinuous part of the turnout system have not been clarified. In this study, analysis of ground vibrations around the improved turnout system is performed in order to predict the generation level of ground vibrations due to the passage of the tilting train through the improved turnout system.
