体外预应力加固法是一种较为常用的公路桥梁施工技术,能有效强化承载力与耐久性有所下降的公路桥梁。在破损公路桥梁随公路交通系统的发展而显著增多的背景下,这种技术得到了越来越广泛的应用,技术的应用范围和成熟程度也获得了相应的提高。本文将探析体外预应力加固法的技术机理和技术特征,并结合相关应用经验,总结其应用于公路桥梁时的技术要点,希望能进一步促进该技术的应用化和普及化,提高我国公路系统的建设水平。 External prestressed reinforcement method is a more commonly used highway bridge construction technology, which can effectively strengthen the bearing capacity and durability of the decline of highway bridges. Under the background that the damaged highway bridges increase significantly with the development of highway traffic system, this technology has been more and more widely used, and the application range and maturity of technology have also been increased accordingly. This paper will explore the technical mechanism and technical characteristics of the external prestressing reinforcement method, and combined with relevant application experience, summarizes the technical points when it is applied to the highway bridge, hoping to further promote the application and popularization of the technology and improve the road system of our country Construction level.
