由于施工质量和桥梁设计等方面的原因,使得桥梁的检测和加固成为必要,并且目前我国已有一定数量的桥梁发生老化,危桥逐年增多,受到当时的设计,材料、施工等方面的影响和局限。先天不足,加上不能适应目前交通量的迅猛增长。使得旧桥的检测和加固技术显得非常迫切。对原有桥梁进行加固补强、改造翻新,最大程度利用现有资源,保证其使用安全,延长其使用寿命是当今工程界关注的重大课题之一。
Due to the construction quality and the design of the bridge, it is necessary to inspect and reinforce the bridge. At present, a certain number of bridges in our country have been aged and the number of dangerous bridges has been increasing year by year. Influenced by the design, materials and construction at the time, Limitations. Congenitally, coupled with the current traffic can not adapt to the rapid growth. Making the old bridge detection and reinforcement technology is very urgent. It is one of the major topics that the engineering community pays attention to to strengthen and reinforce the existing bridges, reform and renovate them, make maximum use of the existing resources, ensure their safe use and prolong their service life.
