“提高旧桥承载能力的加固技术措施”的研究成果,在本刊上已作过了简要的介绍。但为了使这些在旧桥加固或改造中已取得了预期的、明显的技术经济效果的研究成果能尽快地在旧桥加固或改造工程中得到推广应用,现将其中几种主要的旧桥加固或改造技术,作出原则性的规定,提出设计、施工注意要点,供有关人员参考试用。 “Improve the carrying capacity of the old bridge reinforcement technology,” the research results, has made a brief introduction in this magazine. However, in order to make the achievements of the research on the expected and obvious technical and economic results obtained during the reinforcement or renovation of the old bridge be popularized and applied in the reinforcement or renovation of the old bridge, some of the major old bridges are now being reinforced Or transformation of technology, to make the principle of the provisions of the design, construction points of interest for reference for the relevant personnel trial.
