随着预应力技术在各领域应用的不断扩大,预应力技术已经成为工程领域发展最快的一门技术,它在预应力新材料、新技术、新设计方法也不断得到创新发展,在公路桥梁工程中预应力施工及其配套技术已经初步形成,在诸多大型工程项目中已显露头角,发挥了较大作用。结合国内成功案例对预应力技术在公路桥梁中的应用进行总结,对应用关键技术点进行分析。 With the continuous expansion of prestressed technology in various fields, prestressed technology has become one of the fastest growing technologies in engineering field. It has also been constantly innovated in the field of prestressed new materials, new technologies and new design methods. Prestressed construction and its supporting technology has been initially formed in the project, in many large-scale construction projects have been exposed Tau Kok, played a greater role. Combined with the domestic success stories, the application of prestressing technology in highway bridges is summarized, and the key technical points of application are analyzed.
