悬臂拼装法在人民桥扩建稆的应用

介绍了广州市人民桥扩建工程预应力连续梁的分段预制和悬拼施工工艺。指出了箱梁预制，拼装施工中需注意的一些问题，最后介绍了大桥施工监测的项目和程序，拽出确保大桥线型良好、顺利合扰的关键是监控每一节箱梁的中轴线偏位、标高以及在拼装过程中的变化情况。

Application of Fabricated Cantilever Construction Method in Renmin Bridge

In this paper, the construction techniques which are used for the pre_stressed fabrication and assemblage of the newly_built Renmin Bridge in Guangzhou is presented. Some key points in the box_girder pre_cast and assemblage are listed. And the monitoring items and procedures during construction phases are introduced. In order to ensure the geometry of the girder as well as the good connection of the two cantilever ends at the center of span, it is important to monitor the tolerance of axis, elevations and their change of the girder.
