桥梁流固结合支架预压施工技术方案

The Prestressed Construction Plan of Flow-solid Combination Stent in Bridge Construction

南水北调中线京石段向阳大街交通桥施工时，交通桥箱梁的支架施工采用了流固结合的支架预压方法，大大缩短了施工时间，桥梁主体提前两天实现通水目标。本文主要介绍流固结合支架预压施工工艺、理论计算方法及施工过程中的注意事项，为以后类似工程项目施工提供技术支持。

The stents of traffic bridge box beam is constructed in the prestressed method of flow-solid combination in the Xiangyang Street Bridge. It shortened the construction time and realizes the objective of water transfer 2 days before the scheme. It introduced the construction craft, theoretical calculation method and some points for attention of the prestressed stents construction with the method of flow-solid combination.
