A Study of Coupled Behavior of Railway Ballasted Track and Structure by Large Shaking Table Test Using Scale Model

Abstract

At the transition zone between embankment and bridge, lateral resistant force of ballasted track likely to decrease by the deformation of embankment under earthquake. Particularly, under the high temperature in summer season, axle load of rail increases and the risk against rail buckling tend to increase. To evaluate the stability against rail buckling by the deformation of embankment and ballast, shaking table test with coupled scale model of ballasted track and structure was carried out. Reinforcement of embankment and counter measure against rail buckling effectively prevented the rail bucking under the large earthquake.
