[0002] As an important part of road bridges, culverts have different structural forms such as slab culverts, circular culverts, box culverts and arch culverts, all of which have their own applicable scopes. In recent years, the construction and development of mountain roads and a large number of railways have put forward requirements for road lines, and the phenomenon of deep excavation and high filling has inevitably appeared, and the high fill embankments have gradually increased. The reinforced concrete arch culvert converts the upper fill load and live load into the axial force of the arch, which greatly exerts the mechanical properties of the material. It is a structural form with reasonable force and high economic benefits. Due to its good force structure and compressive effect, it is suitable for this kind of high fill roadbed, and at the same time has the advantage of making full use of excavation to reduce abandoned soil.
