随着经济的快速发展,各种公路桥梁不断地增多,桥梁是道路的咽喉,是保证运输正常运行的重要通道,由于桥梁使用后会受到自然环境的侵蚀和过往车辆的磨损,还有设计和建造时人为缺陷,造成了桥梁在使用过程中存在着很大的隐患,为了防止桥梁在使用过程中出现问题,所以对桥梁进行加固,从而提升桥梁的承载能力,以保证道路桥梁的正常使用。为了适应老旧桥梁的维护和改造,不断对桥梁的加固技术进行研究,并取得了很大的进展,但是却忽略了桥梁加固过程中经济利益的考虑,使桥梁维修养护费用居高不下。
With the rapid economic development, various types of highways and bridges are continuously increasing. The bridges are the throat of roads and are important passages for ensuring the normal operation of transportation. Since the bridges are eroded by the natural environment and worn by passing vehicles, the design and The construction of human defects, resulting in the use of the bridge there is a big hidden dangers, in order to prevent the bridge during the use of problems, so the reinforcement of the bridge, so as to enhance the carrying capacity of the bridge in order to ensure the normal use of road and bridge. In order to adapt to the maintenance and renovation of old bridges, the bridge reinforcement technology has been continuously researched and great progress has been made. However, the consideration of economic benefits in the process of bridge reinforcement has been neglected, and the cost of bridge maintenance and repair has been kept at a high level.
