A rail support beam low track and viaduct transition section structure for a medium-low-speed magnetic suspension traffic project. The structure comprises a roadbed, a bridge abutment (2), rail support beams (1), grouting pipes (5), and drainage ditches (7). The bridge abutment (2) comprises an abutment back body (2.1) and abutment cones (2.3). Each rail support beam (1) comprises a bottom slab (1.2) and an upper structure (1.1) disposed on the bottom slab (1.2), and the bottom slab is buried in the roadbed, and the bottom slab (1.2) extends downwards to form tenons (1.3) corresponding to tenon grooves (2.2). Each tenon (1.3) is placed in the corresponding tenon groove (2.2), and round corners are disposed on the tenons (1.3) and the tenon grooves (2.2), so that the tenons (1.3) can rotate in the tenon grooves (2.2). There are multiple grouting pipes (5), and the grouting pipes (5) are disposed in the roadbed. The rail support beams of a low track are in lap joint with the tenon grooves of a viaduct, so that settlement and slab staggering between the low track and the viaduct caused by different foundation treatment measures are avoided, the effect that settlement and slab staggering of a magnetic suspension F rail at the junction position of the low track and the abutment are avoided is ensured, and the requirements for smoothness of the F rail at the transition section between a viaduct structure and the low track of the magnetic suspension traffic project is effectively satisfied.
