• In order to estimate influence on slab track of Shinkansen due to increasing operating speed, we measured stress caused in the slab tracks at train speed from 285 to 395 km/h. As a result of measuring, we found that stress was 3.81MPa or less, and confirmed that it was less than the threshold of speed-up. The threshold of stress caused in slab track PRC type install on the site is 4.7MPa. Next, we investigated the relationship between the stress and speed using the results of measuring, however we did not found constant tendency. Then we looked for other factor which increased the stress caused in slab track. As a result, we found that the stress caused in slab track is influenced by vertical displacement of the edge of the slab track, and that the level of the stress is influenced by difference between maximum and lowest temperature along the day, the influence of it is larger than that of train speed.
