摘要: 通过对长期服役的混凝土坝工作性态健康诊断,有助于选择合适的风险管控措施,保障混凝土坝安全运行。在阐述我国混凝土坝病险隐患的基础上,总结了混凝土坝健康诊断的作用,论述了混凝土坝安全监测和现场检测技术、诊断模型、结构计算及模型试验等关键理论、方法与技术的研究进展。认为今后应加强数据驱动的混凝土坝安全性态时空演变特征提取、可靠度发展模式识别、风险率动态协同评估、多源异构信息融合决策、临界预警阈值拟定等方面的研究,以期全方位地构建数据共享、信息互补的诊断知识工程,确保大坝长效健康服役。

Abstract: Health diagnosis for concrete dams during long-term operations is significant to the choice of appropriate risk control measures. Based on an analysis of the hidden troubles of concrete dams in China, this paper reviews recent advances in the key theories, methods and technologies for dam health diagnosis, including in-situ monitoring, on-site inspection, mathematical modelling, structural simulation, and model tests. We highlight further studies in the future on data-driven temporal and spatial evolution characteristics of concrete dam safety status, pattern recognition of reliability development, dynamic collaborative evaluation of risk probability, multi-source heterogeneous information fusion decision, and critical early warning threshold formulation. They are extremely essential to construct a comprehensive diagnosis knowledge project with data sharing and information complementing in an all-round way, so as to guarantee long-term safe operations of concrete dams.

Key words: concrete dam, health diagnosis, in-situ monitoring, on-site inspection, data driven
