预应力碳纤维板加固系统在连续梁桥跨中下挠加固中的应用

Using of Prestressed Carbon Fiber Plate Reinforcement System for the Deflection of the Mid-span Strengthening of Continuous Beam Bridge

预应力技术为桥梁结构的加固和提载提供了一种主动有效方法。预应力碳纤维板加固系统是最新的有黏结体外预应力技术。结合工程实例,分析了预应力碳纤维板加固系统在连续梁桥跨中下挠加固中的作用。

The prestress technology has been widely used in the civil engineering and provides an active and effective way to strengthen bridge structures. The prestressed carbon fiber plate reinforcement system is the latest external prestress technology. In this paper, we analyse effects of this system for the deflection of the mid-span strengthening in the continuous beam bridge.
