摘要
随着我国社会主义经济的飞速发展,各种重型车辆增多,尤其是工程用重型运输车不断出现,桥梁负荷日趋加重,部分旧桥老化、破损严重,设计荷载等级已不能满足使用要求,因此公路路桥的建设与维护变得十分重要。结合工程实际进行关键技术的分析,总结出体外预应力加固技术的施工要点,可为相关工程提供一定的参考。
With rapid developing of socialist economy, various heavy vehicles appear, especially engineering- use heavy vehicles. Bridges are bearing more and more loading. Some bridges have been seriously destroied, and their design loading levels have not be able to meet the using demand. Therefore, construction and maintenance of highway and bridge become very important. technologies of construction and summarizes main provides a certain reference for similar projects. Combining with project practice, the paper analyzes key points of external prestress strengthening technology, which
