旧桥加固技术是一门新的课题。目前,我国公路交通事业蒸蒸日上,不少高速公路已建成投入运营中,还有不少正在建设的高速公路和其它等级的公路也即将建成投入运营。但是,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,更因为建国以来所修建的不少旧桥,由于受到当时的设计、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。现就这些问题进行分析,并提出一些有利的措施使我国的桥梁加固技术得以完善。 Old Bridge reinforcement technology is a new topic. At present, China’s road transport industry is booming. Many highways have been put into operation. Many highways under construction and other types of highways are about to be built and put into operation. However, because of the construction quality and the design of the bridge, the detection and reinforcement of the bridge are necessary. Moreover, many old bridges built since the founding of the People’s Republic of China were influenced and limited by the design, materials and construction at that time. Congenitally, coupled with the current traffic can not adapt to the rapid growth, making the old bridge detection and reinforcement technology is very urgent. These problems are analyzed and some favorable measures are proposed to improve the bridge reinforcement technology in our country.
