摘要：

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. 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. Secondly, the mechanical properties of typical integral and circular hinged box cults are studied by finite element simulation. 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. The research results show that the failure modes of all four types of components are bending failure of the concrete at the bottom of the upper roof after cracking, but the setting of hinge joints significantly changes the stress state of the box culvert structure, especially the stress state of the side wall. The bearing capacity is similar to that of cracking load, that the integral box culvert structure has the maximal bearing capacity and circular hinged box culvert structure has the the minimal capacity. © 2020, Jilin University Press.
