摘要:
针对预应力混凝土结构耐久性的现实问题和未来矛盾日益突出的趋势，对预应力混凝土结构耐久性的研究进展进行了系统梳理和总结。提出了预应力混凝土结构耐久性的研究体系，包括研究背景、对象、思路、目标、科学问题、技术问题、内容、技术路线等；对预应力混凝土结构耐久性问题的研究现状分5个方面进行了综述，包括混凝土损伤有关耐久性问题、预应力钢筋腐蚀有关耐久性问题、锚固连接体系腐蚀有关耐久性问题、耐久性测试和提升及试验技术、耐久性数值模拟技术；提出了7个有关预应力混凝土结构耐久性研究尚需进一步解决的问题，即环境作用定量模型、腐蚀介质传输行为、腐蚀疲劳损伤演化模型、锚固连接体系腐蚀行为、岩土预应力结构的腐蚀行为、耐久性提升技术、耐久性数值模拟技术。所做研究可为进一步拓展和完善预应力混凝土结构耐久性研究提供参考。
Abstract:
Aimed at the existing problems and future requirements on the durability of prestressed concrete (PC) structures, the research proceeding on durability of PC structures was summarized systematically and analyzed. The research system of the durability of PC structures was put forward, where the research background, objects, clue, aim, scientific issues, technological issues, contents and technical lines were concerned in. The state-of-the-art of the research was reviewed as five parts: the issues of durability about the damage of concrete, the issues of durability about the corrosion of steel bars, the issues of durability about the corrosion of anchorage and joint system, the technology of testing, raising and experiment of durability, and the technology of numerical simulation of durability. Seven issues about the durability of PC structures, which needed more research work, were suggested. The issues included the quantitative models of environmental action, the transporting behavior of corrosive mediums, the evolving models of corrosion fatigue damage, the corrosion behavior of anchorage and joint system, the corrosion behavior of geotechnical PC structures, the technology of raising durability and the technology of numerical simulation of durability. The study can provide references for further expanding and improving the research work on durability of PC structures.
