Abstract Research purposes:When the terminalofballastless track bridge produces some deformation, the fastenings near the bridge jointwill produce additional force. The fastening is an importantpartof the ballastless track to transfer the force. Both the toe load of fastening and pressure deformation of resilient pad have corresponding limits, so it is necessary to analyze the additional force of fastening near the bridge join.t
Research conclusions:Combinedwith bi-block ballastless track ofZhengzhou-Xican PassengerDedicated Line, this paper calculates the additional force of fastenernear the bridge jointwith the finite elementanalysismethod. The result indicates that the additional force of fastenerproduced by bridge deformationwillmake influence on choosing the type of fasteners near the bridge join.t
