摘要
混凝土耐久性能不良引起的适用性、安全性问题以及由此引发的环境、能源、经济问题在全球范围内已引起广泛的关注。而沿海城市经济的飞速发展和大规模的开发海洋资源使得混凝土结构面临严峻的海洋环境的挑战。因此,了解沿海混凝土结构耐久性问题的研究现状与对策具有十分重要的现实意义。综合分析了沿海砼结构性能退化的原因及解决办法并在此基础上指出进一步研究的可能方向。
The applicability and safety problems caused by the undesirable durability of reinforced concrete have drawn a worldwide attention, and the quick development of coastal urban economy and large-scale exploitation of marine resources have made the reinforced concrete structures face serious challenge of marine environment, so to keep informed of the study and measures for solving the durability problem of coastal reinforced concrete structures is of great significance. In this paper, the causes and solutions for performance degradation of coastal reinforced concrete structure are comprehensively analyzed, and the ways to further study the durability problem are also pointed out.
