Abstract Research purposes: Frame-slab track is a new kind of track and has been applied in Guangzhou-Zhuhai Intercity Rail Transit, but the method of systemic design has not been established. This paper sets up the calculation model and method of the frame-slab track, predominates the rule of force and deformation of frame-slab track， provides support for the frame-slab track design.
Research conclusions : Frame-slab track is be provided with favorable technical and economy, frame-slab is benefit to reduce the influence of wrap deformation of slab. The model calculation model and analysis method established in this paper take in count of the load of train, temperature load and asymmetry settlement, bend of bridge, etc. can systemically analyse the frame-slab track , predominate the rule of force and deformation. By analysis the influence of design parameter to force and deformation，this paper draws a conclusion that the force and deformation of the slab bottom is decrease with the accretion of elastic modulus of CA sand mortar, and increase with the accretion of stiffness of fastener and settlement of substructure.
