随着公路交通运输量不断增加,公路桥梁负荷日趋加重,加之旧桥部分老化、破损或受原设计标准的限制,已不能适应现代交通运输的要求,迫切需要对其进行技术改造,尤其是采用加固补强等方法来恢复、提高其承载力。结合实际经验就公路桥梁加固施工技术进行了论述。 With the increasing traffic volume on highways, the load on highways and bridges is aggravating day by day. In addition, due to the aging, breaking down or being restricted by the original design standards, the old bridges can no longer meet the requirements of modern transportation and there is an urgent need to reform them. In particular, Reinforcement and other methods to restore and enhance its carrying capacity. Combining with practical experience, this paper discusses the construction technology of highway bridge and bridge reinforcement.
