斜拉加固模板体系在片石混凝土桥台施工中的运用

Application of Cable-stayed Reinforcement Formwork System in Construction of Rubble Concrete Abutment

目前,片石混凝土桥台模板加固方法普遍采用对拉体系,但该方法施工质量不易控制。基于此,该文结合渝黔复线高速公路连接道工程中片石混凝土桥台施工实例,介绍了一种能够显著提高片石混凝土桥台施工质量的斜拉加固模板体系,分析其模型验算及施工工艺并与传统对拉加固体系进行对比,总结其优点及经济效益,可为类似混凝土桥台模板加固工程提供一定参考。

At present,the formwork reinforcement method of rubble concrete abutment generally adopts the split system,but it is not easy to control the construction quality.For that,combined with the construction case of rubble concrete abutment in the road connection project of Chongqing-Guizhou double track expressway,this paper introduced a cable-stayed reinforcement formwork system,which can significantly improve the construction quality of rubble concrete abutment,compared it with the traditional tension reinforcement system,and analyzed its advantages and economic benefits.It can provide some reference for similar concrete abutment formwork reinforcement projects.
