Heavy haul railway with large axle loads is more appropriate for freight transportation trainloads,due to its larger transport capacity,higher efficiency and lower transportation costs. In this paper,reinforced concrete slab culvert in railway is studied through site investigation,calculation and analysis. Corresponding strengthening methods are presented including reinforcement with steel plate,increase of cross-section,local frame reconstruction,shortening of span,reinforcement with inner sleeve frame,and replacement of frame and so on.
