Abstract:The prefabricated socket-type pier has the advantages of convenient construction, large allowable error and reliable node. In order to promote the engineering application of this prefabricated pier in China, relying on a expressway reconstruction and extension project and based on ABAQUS finite element calculation platform, the full-scale solid modeling of prefabricated bridge connected by socket and spigot joints in the project is carried out. At the same time, the finite element model of cast-in-place bridge pier with the same size is established. And the monotonic displacement loading is carried out on the both. The numerical simulation results show that the socket-type connection is basically similar to the cast-in-place connection, and has the good mechanical performance. It can be considered as equivalent to the cast-in-place connection in practical projects, and has the great promotion value.
