随着我国社会经济和交通运输事业的快速发展,过去年代修建于各级公路上的桥梁担负着十分沉重的交通荷载和繁重的交通道口。由于历史的种种原因,如建桥当时的资金紧缺,设计荷载及泄洪能力偏低,技术力量的缺乏,设计、施工管理的粗放,设计、施工技术水平较低和设备、手段、材料的落后,以致在设计上或多或少存在一些缺点,施工也留下不同程度的缺陷。为此,本文首先讨论了桥梁加固与维修的适用范围和加固原则,接着分析了桥梁健康安全检测和桥梁维修加固,最后做了总结。因此本文具有深刻的理论意义和广泛的实际应用。
With the rapid development of social economy and transportation in our country, bridges built on roads at various levels in the past have been shouldering heavy traffic loads and heavy traffic crossings. Due to various historical reasons, such as the shortage of funds at that time, the low design load and discharge capacity, the lack of technical strength, the extensive design and construction management, the low technical level of design and construction and the backward equipment, methods and materials, So that there are some shortcomings in the design more or less, construction also left varying degrees of defects. To this end, this paper first discusses the application of reinforcement and repair of bridges and reinforcement principles, and then analyzes the bridge health and safety inspection and bridge maintenance and reinforcement, and finally concludes. Therefore, this article has a profound theoretical significance and a wide range of practical applications.
