Construction of the integrated technology for the extension of life ofexisting concrete structures

这项研究工作的目标是建立既有劣化混凝土结构维修的综合技术，延长基础设施的使用寿命。这一集成技术由三项基本技术组成。即：(1)既有混凝土结构材料劣化诊断技术；(2)劣化结构剩余承载能力评估技术；(3)新材料修复加固技术的发展。通过整合这三项基本技术，我们为基础设施的维护提出了切实有效的措施。

The target of this research work is to build the integrated technology for the maintenance of deteriorating existing concrete structures and to extend the life of infrastructures. This integrated technology is comprised of three elemental technologies. Namely, they are (1) the deterioration diagnosis technology for materials of existing concrete structures, (2) the evaluation technology for remaining load carrying capacity of deteriorated structures, and (3) the development of various repairing or strengthening techniques using new materials. By integrating these three elemental technologies, we have proposed practical and usefulmeasures for the maintenance of infrastructures.
