大量水工混凝土结构存在裂缝、侵蚀、冻融、热疲劳、碳化等隐患。这些隐患严重影响结构的强度、稳定性和耐久性。目前对这些问题的研究主要采用单一的监测或诊断方法。多种监测诊断方法的集成应用还不广泛。此外，对这些问题的分析理论还不完善。目前对水工混凝土结构的老化机理、时变模型和健康诊断等方面的系统研究还很不够。对工程实践的支持是有限的。针对这些重大科技问题，结合具体工程，开展了水工混凝土结构隐患检测与健康诊断研究。本文的研究内容包括：水工混凝土结构隐蔽缺陷的现场无损检测、渗漏检测、现场监测系统的建立、现场检测与现场监测相结合、水工混凝土结构的开裂、冻融、侵蚀、碳化机理、组合老化机理;水工混凝土结构的时变模型，水工混凝土结构健康诊断的理论与方法。
A large number of hydraulic concrete structures have hidden defects such as cracks, erosion, freeze and thaw, thermal fatigue, carbonization. These hidden defects seriously affect the strength, stability and durability of structures. These problems are studied mainly by single monitoring or diagnosis methods at present. The integration of multiple monitoring and diagnosis methods is not applied widely. Besides, the analysis theory on these problems is not developed very well. The systemic study on the aging mechanism of hydraulic concrete structures, time-variation model and health diagnosis is still not enough. The support for engineering practice is limited. Aimed at these major scientific and technological problems and combined with specific projects, study on detection of hidden defects and health diagnosis of hydraulic concrete structure has been carried out. This study includes the following content: field non-destructive examination of hidden defects of hydraulic concrete structures, seepage detection, the construction ofin-situsensing system, the combination of field detection andin-situmonitoring, the mechanism of crack, freeze and thaw, erosion and carbonization of hydraulic concrete structure, mechanism of combination aging; time-variation model of hydraulic concrete structure, theories and methods for health diagnosis of hydraulic concrete structures.
