abstract="Uneven subgrade settlement associated with rail deflection occurs mainly in the bridge-embankment transition zones of high-speed railways. An iterative method of computation is proposed for studying such uneven settlement in these zones. A vehicle-track-subgrade model is used to investigate the vehicle-track interactions and the deviator stress field of the transition zone, and a soil cumulative plastic strain model is used to obtain the deterioration process of uneven settlement in the transition zone. <br><br>RESULTS indicate that uneven settlement caused by train loads in the transition zone tends to plateau at 40,000 repeated load applications. Subgrade settlement changes abruptly in the first measured 5 m, as well as from 25 to 30 m from the abutment; these two regions should be adequately strengthened and should receive more attention for track maintenance.<p /> <p>Language: en</p>",
