摘　　要：标准化节段预制拼装箱梁相对于传统现浇箱梁,能够极大地提高施工质量及施工进度。剪力键是节段预制拼装箱梁的重要传力构造。该文基于实际的工程项目,分析了节段预制拼装箱梁不同位置剪力键的受力性能差异及不同键齿数量条件下的剪力键受力性能差异。Compared with the traditional cast-in-place box girder, the standardized prefabricated segmental erected box girder can greatly improve the construction quality and construction progress. The shear connector is an important force transferring structure of prefabricated segmental erected box girder. Based on the actual project, this paper analyzed the difference of the mechanical behavior of shear connectors at different positions and those under the condition of different numbers of shear connectors.
