多跨简支连续分布式箱梁桥合理施工工序研究

摘要

以某高速公路一先简支后连续预应力箱梁桥为背景,分析了关键截面的挠度随不同施工工序的变化情况,进而探索最优施工工序,为箱梁桥快速、高效的施工提供了保障。%Taking the simply supported continuous prestressed box-girder bridge on the highway as the background,the article analyzes the changing conditions of critical section deflection according to different construction process,and further explores optimal construction process,which has provided fast and high efficient guarantee for the box-girder bridge construction.
