随着时间的推移和经济的发展越来越多的桥梁不适应交通的需要。桥梁的加固和维修是解决这个问题的主要方法之一。所以桥梁的加固和维修已经成为工程的热点问题。本文总结了一些桥梁的常见病害和加固方法,体外预应力加固技术通过运用体外预应力加固法加固后的桥梁加固之前静载试验与动载试验的桥梁结构状态进行了对比分析和研究。结果表明,对现有的桥梁出现的病害,进行科学的检测和研究分析,并进行体外预应力方法的加固改造,可以有效地恢复其承载能力,对消除交通隐患、提高通行能力和服务水平都具有重要的意义。
With the passage of time and economic development, more and more bridges are not suited to the needs of transportation. Bridge reinforcement and repair is one of the main ways to solve this problem. Therefore, the bridge reinforcement and repair has become a hot issue of the project. This article summarizes some common diseases and reinforcement methods of bridges. The external prestress reinforcement technology is compared and analyzed by using the prestressed reinforcement method and the comparison of the bridge structure state between static load test and dynamic load test before the reinforcement of the bridge. The results show that the detection and analysis of the existing diseases of the bridge, and the reinforcement and reconstruction of the external prestressing method can effectively restore the bearing capacity of the bridge, eliminate the traffic hazard, improve the traffic capacity and service level It is of great significance.
