摘要
目前钢箱梁已得到广泛应用,且多采用体外预应力体系,就其结构形式、工艺特点、材料规格,在城市桥梁建设中具有显著特点,体外预应力也逐渐成为预应力技术热点。本文结合工程实例,对刚箱梁体外束预应力施工作一详细介绍,与大家共同探讨。
The steel box girder has been widely used,and is often used for externally prestressing system.Due to its structure,process characteristics and material specifications,it has a distinctive feature in bridge construction in the city.And the external prestressing force has become a pre-stressed technology hot spot.In this paper,with the project examples,the implementation of externally prestressing system of steel box girder is described to discuss with peers.
