摘要
在我国现代交通运输体系中,桥梁是非常重要的一部分,可以说桥梁工程事业的发展有效的推动了我国社会与经济的发展。在桥梁工程施工中,新技术、新材料和新工艺的应用极大的提升了桥梁整体质量,使现代桥梁具备更大的承载能力。预应力应用于桥梁施工中,在结构承受外界载荷之前,提前对钢筋施加了压力,这样就能够确保在外界载荷对结构施加压力时,混凝土内部产生的应力会抵消载荷的拉应力,从而更好地控制混凝土结构裂缝。本文对预应力技术在桥梁工程施工中的应用进行了探讨和分析,仅供参考。
In China’s modern transportation system, bridges are a very important part. It can be said that the development of bridge engineering has effectively promoted China’s social and economic development. In the construction of bridge projects, the application of new technologies, new materials, and new processes has greatly improved the overall quality of the bridge, making modern bridges have greater bearing capacity. By applying prestress to bridge construction, before the structure is subjected to external loads, pressure is applied to the steel bars in advance, which can ensure that when the external load exerts pressure on the structure, the stress generated in the concrete will offset the tensile stress of the load, which can better control concrete structure cracks. This article discusses and analyzes the application of prestressed technology in the construction of bridge engineering, for reference only.
