现代预应力技术推动了土木工程的快速发展,同时也是当今大型结构,特别是桥梁施工中应用最为广泛的科学技术。随着预应力技术的发展,新的预应力材料和锚固体系的出现,使得这一技术和方案的应用前景非常广泛。文章结合南水北调中线工程新郑南段桥梁施工特点,对预应力技术在桥梁施工过程中的应用加以阐述。
Modern prestressing technology has promoted the rapid development of civil engineering. It is also the most widely used science and technology in large structures, especially bridge construction. With the development of prestressing technology, the emergence of new prestressed materials and anchoring systems makes the application of this technology and solution very promising. In this paper, the application of prestressing technology in the process of bridge construction is described based on the characteristics of bridge construction in Xinzhengnan Section of the midline of South-to-North Water Diversion Project.
