摘要:
对国内外冻融环境下混凝土结构耐久性研究现状及发展趋势进行了系统的总结及归纳,并对该领域未来研究方向进行了展望.基于对国内外文献的研读与分析,首先对冻融环境下混凝土的破坏机理、冻融试验方法和标准进行了归纳与梳理;并分别从理论研究及数值模拟方法上对非预应力混凝土结构、预应力混凝土结构耐久性研究方法进行归纳总结,同时提出增强混凝土抗冻性能的对策措施,最后分析了未来冻融环境下混凝土结构的耐久性研究趋势.研究表明:针对冻融环境作用下混凝土结构耐久性研究已取得一定的研究成果,但基于大尺寸预应力构件开展的冻融环境作用下的耐久性研究尚未见报道,应作为下一步重点研究的方向.
Abstract:
The research status and development trend of the durability of concrete structures under freeze-thaw environment at home and abroad are systematically summarized and summarized, and the future research direction in this field is prospected. Based on the study and analysis of domestic and foreign literature, the freeze-thaw environment The failure mechanism of concrete, freeze-thaw test methods and standards are summarized and sorted out; and the durability research methods of non-prestressed concrete structures and prestressed concrete structures are summarized from the theoretical research and numerical simulation methods, and the enhancement Finally, the research trend of the durability of concrete structures under the freeze-thaw environment is analyzed. The research shows that some research results have been achieved in the study of the durability of concrete structures under the action of freeze-thaw environments, but based on the large-scale prediction The durability research of stress components under the action of freeze-thaw environment has not been reported yet, and it should be taken as the next key research direction.
