摘要：

介绍了短线匹配法预制悬拼施工技术的特点、工艺原理、控制要点,结合苏通大桥施工实例,重点分析了箱梁施工中受力特点和线形控制要点以及改进措施,为其它类似工程提供一些借鉴。

The authors describe the features,technological principle and control points of the technology for prefabrication and suspended splicing of box girders with a segmentation method and,in the light of the construction of Sutong Bridge,focus on the analysis of the characteristics of box girders under stress and the key points of linear control of box girders in the process of prefabrication as well as the measures to improve the technology.The analysis and discussions may offer some reference for similar projects.
