在水利部前期重大项目“地震对大坝灾变机理与对策研究”、国家自然科学基金项目“基于FEMOL的大口径PCCP管结构计算与安全评价”、中央级公益科研院所专项资金重点项目“高坝全级配混凝土动态性能与灾变过程模拟”、南京水利科学研究院院基金项目“高坝混凝土断裂损伤与动力灾变机理研究”等的资助下,历时8年完成的水工混凝土静动态损伤断裂过程及其声发射特性方面研究成果的总结.项目组开发了混凝土损伤断裂精细化测试系统:该系统具有量程大、精度高、多参数同步采集并输出、实时监控兼有声发射量测等功能,取得国家发明专利;历时8年系统开展了各类混凝土静动态损伤断裂过程试验:共计完成了近300根普通混凝土(含标准试件、非标准试件)、钢筋混凝土、碾压混凝土等一系列试件的
In the previous major projects of the Ministry of Water Resources, “Research on Mechanism and Countermeasures of Calamity Caused by Earthquakes”, National Natural Science Foundation of China, “Calculation and Safety Assessment of Large-caliber PCCP Pipe Structures Based on FEMOL”, Special Fund for Central-level Public Welfare Research Institutes Key project “high dam full grade concrete with dynamic performance and catastrophe simulation ”, Nanjing Academy of Hydraulic Research Fund Project “high dam concrete damage damage and dynamic catastrophe mechanism ” and other funded, took 8 years to complete The project team has developed a concrete damage fracture fine testing system: The system has a large range, high precision, multi-parameter synchronous acquisition and output, real-time monitoring Both acoustic emission measurement and other functions, made the national invention patents; lasted for 8 years to carry out a variety of static and dynamic damage to the concrete test process: a total of completed nearly 300 ordinary concrete (including standard specimens, non-standard specimens), steel Concrete, RCC and a series of specimens
