装配式预应力混凝土小箱梁横隔板设置

随着装配式预应力混凝土小箱梁在桥梁工程中的广泛应用，是否在跨中设置横隔板以约束箱梁的扭转等畸变效应逐渐引起设计人员的注意。以实践中的简支小箱梁为例，采用ANSYS有限元软件对是否在桥梁跨中设置中横隔板的不同情况进行对比分析，结果显示跨中横隔板的设置能改善上部结构的整体性。

Study on Installation of Diaphragm for Prefabricated Prestressed Concrete Box Girder

With the extensive use of the prefabricated prestressed concrete box girder in the bridge engineering projects, the installation of the diaphragm restraining the deformation of the box girder is gradually brought to the attention of the designers. Using the simply supported small box girder in the actual project as an example, in this article, the different cases of the installation of the diaphragm have been compared and analyzed by means of ANSYS programming. It has shown that the installation of the diaphragm can improve the integrity of the bridge superstructure.
