当前,随着我国经济的快速发展,以汽车为主要交通工具的时代,公路的承载量愈来愈大,在公路运输中,桥梁在其中起到非常重要的作用,建设桥梁非常困难,即使在施工过程中人们极力保证其工程的质量,但是由于汽车和大型运载车辆长期的碾压,知识桥梁或多或少发生损坏,这种情况是无法避免的。所以,为了能够保证桥梁在使用过程中充分发挥作用,并且能够在长期使用的基础上,减小其损害,这是管理部门亟需解决的问题。在桥梁建设过程中,对其进行加固处理至关重要,也就是在进行加固处理过程中,需要通过预应力技术来改变桥梁结构的受力情况,从而提高桥梁的承栽力。本文就预应力技术在桥梁结构加固施工中的应用做一个简要分析。 At present, with the rapid economic development in our country and the age of automobile as the main means of transport, the carrying capacity of the road is getting bigger and bigger. In the road transportation, the bridge plays a very important role in it. It is very difficult to build a bridge. In the course of construction, people try their best to ensure the quality of their works, but due to the long-term rolling of vehicles and large vehicles, the knowledge bridges are more or less damaged, which is unavoidable. Therefore, in order to be able to guarantee the full use of the bridge during its use, and to reduce its damage on the basis of long-term use, this is an issue urgently to be solved by the management. In the course of bridge construction, it is very important to reinforce the bridge. In other words, during the reinforcement process, the prestressing technology needs to be adopted to change the force of the bridge structure so as to improve the bearing capacity of the bridge. In this paper, a brief analysis of the application of prestressing technology in bridge structure reinforcement construction is made.
