Abstract

Recently, many countries are interested in development of high speed train. However, compared to high speed train technology that is developing, high speed train infra system is not verified. Furthermore, in case of bridge-earthwork transition zone that is the most complicated in railroad facility track, bridge-earthwork is connected complicatedly. Disorder and destruction of track can be occurred by rigidity transition. In order to apply high speed train with 430km/h, it is needed to evaluate stability of behavior condition of bridge-earthwork transition zone by instrumentation system and the construction methods that are accurately and consistently verifiable. In this study, vertical displacement of bridge-earthwork that connects pre-stressed concrete box bridge and earthwork zone is calculated theoretically, and evaluates stability compared with measurement of wheel load, strain, displacement data with estimation data and criteria of measurement. Therefore, as a result of comparing wheel load, strain, displacement data with estimation data and criteria of measurement, the stability showed favorable results.
