Finally, based on the test data and numerical simulation results, the mechanical properties of the four types of box culvert structures are analyzed and compared comprehensively, and some useful suggestions are given. Secondly, the mechanical properties of typical integral and circular hinged box cults are studied by finite element simulation. Firstly, the scale models of four kinds of culvert structures are constructed according to the similarity theory, and the static responses of these models in the full loading process are tested. In order to provide basic data and technical support for the optimal design of prefabricated culvert, the mechanical properties of four types of culvert structures, namely, integral, flat-joint, circular hinge and tenon, are compared and analyzed by means of laboratory test and finite element analysis based on physical engineering.
