The concrete track has been developed as an alternative to the ballast track due to its excellent maintenance. Recently, QHT(Quick Hardening Track) has been developed to rapidly replace ballast track to slab track. In bridge section, post-installation anchors should be installed at the center of QHT segment in order to unify the behavior of bridge and QHT. In this study, track-bridge interaction analysis was performed to check safety of anchor considering at early age of QHT.
