열차이동하중에 따른 박스구조물 동적영향 수치해석 분석

초록

This paper systematically analyzed the dynamic effects of precast box structure - expecting to have direct effect of train loads - according to train's acceleration as it will be located in a section where the acceleration of high speed railway vehicle and the train's operating speed happens. In addition, through the examination of the dynamic effects of the train loads, dynamic behavioral characteristics of embedded structure and vicinity roadbed were analyzed and numerical analysis has been carried out in order to evaluate the performance of track subgrade and the safety of the structure. As a result, we reached the conclusion that the dynamic effects according to the train loads is low, but vertical acceleration occures somewhat high.
