The invention discloses a high-speed railway long-span bridge unit-type ballastless track seamless line design method. The method includes applying ANSYS software and ABAQUS software to respectively establish a high-speed railway long-span CRTS I-type plate-type or double block type ballastless track seamless line vertical and horizontal vertical space coupling static model and a vertical and horizontal vertical space coupling dynamic model. Composition of structures of steel rails, fasteners, track plates, mortar filling layers, base plates, concave retaining platforms, resin filling layers around the concave retaining platforms, double block type sleepers, roadbed plates, isolating layers, limiting grooves, rubber backing plates, supporting layers, bridges, piers and the like and action of high-speed vehicles are taken into consideration, and stress and deformation of tracks and bridge details can be obtained by calculating contractility, deflection force and braking force under different conditions of vert
