随着我国经济的不断发展,对于货物的交流效率要求越来越高,为了能够有效提升我国铁路、公路的承载水平,从而增加运输效率,可以通过提高运输车辆车轴重的方法来达到目的,但是当车轴重量增加就会出现桥梁承载力不足的问题,所以说对于桥梁建筑过程中,体外预应力加固法就是处理上述问题的有效措施之一。本文就该点开展对桥梁体外预应力加固法的研究,对于其中的关键技术进行阐述,为相关专业提供参考依据。
With the continuous development of economy in our country, the requirements for the efficiency of cargo exchange are getting higher and higher. In order to effectively increase the carrying capacity of railway and road in our country and increase the transportation efficiency, we can achieve the goal by increasing the axle load of transportation vehicles. However, When the weight of the axle increases, the problem of insufficient bearing capacity of the bridge occurs. Therefore, in the bridge construction process, the prestressed reinforcement method is one of the effective measures to deal with the above problems. In this paper, we carry out the research on the reinforcement method of external prestressed bridges in this area, and elaborate on the key technologies therein, which can provide references for the related majors.
