本文介绍了韩国首次在设计时速350公里的高速铁路上以430公里/小时的速度进行提速试验。并对路基振动加速度数据进行了分析。在韩国，由于没有进行过试验，因此几乎没有关于铁路速度超过350 m/h的路基行为测量的参考文献。因此，在测量EMS和ICP类型之后，通过交叉检查来自各个传感器和测量装置的数字/值，确认了试验的可靠性。研究结果表明，与HEMU-430X加速时的振动加速度相比，振动加速度值小于12%。此外，混凝土道床轨道的HSB值为标准的52%。结果表明，过渡区路基振动加速度性能评价均在标准规定范围内。
This paper is about the first experiment in Korea that was conducted on speeding increase up with rail speeds at 430㎞/h at high speed railway of designed 350㎞/h. and analysis data collected on vibration accelerations of roadbed. There are barely references on roadbed behavior measurement with rail speeds more than 350 ㎞/h in Korea as it has never been conducted the experiment on it. So the experiments were confirmed the reliability through cross-checking the figures/values from respective sensors and measuring devices after measuring EMS and ICP types. Based on the study, values of vibration acceleration were less than 12% compared with the ones that conducted while speeding up of HEMU-430X. Also, figures of HSB for concrete bed tracks were 52% against the standard. According to the results, all the performance evaluation of vibration acceleration for roadbeds in transition zones is under the standard.
