高原既有桥梁病害维修加固技术研究

Research on Plateau Bridge Diseases Maintenance and Reinforcement Technology

随着经济的不断发展,人们的生活水平也在不断的提高。近些年城市建设也有了显著的提高,而对于连接城市与城市之间的道路和桥梁等,为广大人民群众提供便利交通条件的同时,也为城市建设做出了卓越的贡献,与此同时对城市各行各业的发展也起到了推动作用。近些年随着城市建设的加快,对公路桥梁的构造也提出了更高的要求,同时对既有桥梁的病害维修和加固等也提出了较高的要求,由于我们国家地质条件多以山河为主,所以对于既有桥梁的维修和加固技术相对难度较大。本文中对高原既有桥梁病害维修加固技术做了相关的研究,希望能够通过分析和研究相关的加固技术对青藏高原的道路建设有一定的帮助,从而推动社会经济的发展。文中首先对青海地区既有桥梁使用现状做了分析,接着提出了高原既有桥梁改造加固方案设计,最后以工程案例的形式做了进一步的分析,以供同行商榷。

With the continuous development of the economy, people’s living standards are constantly improving. In recent years, urban construction has also been significantly improved. Roads and bridges while connecting cities,provide convenient transportation conditions for the masses of the people and have made outstanding contributions to urban construction. It has also promoted the development of all walks of life in the city. In recent years, with the acceleration of urban construction, higher requirements have been put forward on the construction of highway bridges. At the same time, higher requirements have been placed on the maintenance and reinforcement of existing bridges.Because China’s geological conditions are mostly mountains and rivers, it is relatively difficult to repair and reinforce existing bridges. In this paper, relevant research on the repair and reinforcement technology of bridge disease in the plateau has been done. It is hoped that the reinforcement and construction technology can help the road construction of the Qinghai-Tibet Plateau to promote social and economic development. In the paper, the current situation of the existing bridges in Qinghai was analyzed. Then the design of the existing bridge reconstruction and reinforcement scheme was proposed. Finally, further analysis was carried out in the form of engineering cases for peer discussion.
