体外预应力加固技术是为提高公路桥梁承载力而产生发展的一项新型技术,是一项区别于传统加固技术的结构体系,是主要以高强度、韧度钢材等为主要原料,对桥梁的主要受力部位进行加固稳定。体外预应力加固技术作为一项创新性技术,利用公路桥梁主要受力结构对原材料增强预应力,提高桥梁内部粘合预应力。它与构件的弧度形状无关,而与桥梁的承载能力、原材料、车流量等密切相关,本文结合工程实例探讨了体外预应力加固技术在公路桥梁施工中的具体应用,希望能对类似的工程提供借鉴。
External prestressed reinforcement technology is to improve the bearing capacity of highway bridges and development of a new technology is a structural system that is different from the traditional reinforcement technology is mainly to high strength, toughness steel as the main raw material, the bridge The main stress site reinforcement and stability. External prestressed reinforcement technology as an innovative technology, the use of the main bridge-bearing structure of the main force of raw materials to enhance prestress, to improve internal bonding prestressed bridges. It has nothing to do with the arc shape of the component, but with the bearing capacity of the bridge, raw materials, traffic flow is closely related to this project combined with engineering examples discussed the application of external prestressing reinforcement technology in highway bridge construction, hoping to provide similar projects Learn from
