随着人们消费观念的改变,采用预应力加固法也越来越广泛,这种方法不仅施工方便、经济,而且加固效果好尤其是当预应力加固筋的布置与外弯矩图形相似,此法既可大幅度提高原梁的受弯承载力,又可显著提高原梁的受剪承载力,对预应力技术在加固设计和施工方面的应用做了进一步探讨。该技术在我国的快速发展和应用,解决了工程中的许多难题,其综合经济效益和社会效益显著。所以推广普及应用混凝土技术成了当务之急。
With the change of people’s consumption concept, the prestressed reinforcement method is also more and more widely. This method is not only easy to construct and economical, but also has a good reinforcement effect. Especially when the arrangement of prestressed reinforcement bars is similar to the graph of the external bending moment, It not only can greatly improve the flexural capacity of the original beam, but also can significantly improve the shear capacity of the original beam. The application of prestressing technology in reinforcement design and construction is further discussed. The rapid development and application of this technology in our country solved many problems in the project, and its comprehensive economic and social benefits were remarkable. Therefore, popularization and application of concrete technology has become a top priority.
