Abstract：Research purposes: The intercity rail transit is mainly constructed on bridge with ballastless track to save land and reduce the influence of ballast dust on environment． When the CRTS I slab ballastless track is designed on the bridge for the intercity rail transit，the node space of fastening at beam gap cannot meet the specification requirements of 650 mm due to the small radius curve．This influences the implement of design scheme of ballastless track on bridge，SO the research is done on finding out a feasible design scheme to solve the problem of node space of fastening at the end of the beam．
Research conclusions: Through analyses and researches on the design parameters，design conditions and evaluation indexes for the rail deflection，elastic breaking—up space of widened rail when the rail broken at beam gap and shearing stress at end of concrete slab．and analyses of the stressed situation of track structure on the node space of fastening at end of beam，this paper proposes a feasible design scheme that the node space of fastening at the end of beam can be up to 725 mm．This breaks through the stipulation of the relative code，but solves the problem that the node space of fastening at the end of the beam influences the implement of track design scheme when ballastless track is used Oil bridge．
